      From Wikipedia, the free encyclopedia\n
      \n
      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
      \n
      ### Rules\n
      \n
      - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    Good morning all, in today’s episode of “What I learned during work hours”…\n
    \n
    I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
    \n
    A quick duckle pointed me to e2image, which says in the man:\n
    \n
    > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
    \n
    I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
    \n
    The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
    \n
    Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
    \n
    Apparently I was being a derp somehow. …Anyways,\n
    \n
    My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
    \n
    I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      From Wikipedia, the free encyclopedia\n
      \n
      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
      \n
      ### Rules\n
      \n
      - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
      - No misinformation\n
      - No NSFW content\n
      - No hate speech, bigotry, etc\n

    Good morning all, in today’s episode of “What I learned during work hours”…\n
    \n
    I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
    \n
    A quick duckle pointed me to e2image, which says in the man:\n
    \n
    > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
    \n
    I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
    \n
    The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
    \n
    Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
    \n
    Apparently I was being a derp somehow. …Anyways,\n
    \n
    My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
    \n
    I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    May I point out that all a RAID1 does is sync the blocks between two drives. It won’t protect against writing something dumb that would mess up the filesystem, it will just dutifully sync it.\n
    \n
    You *should* be able to back up ext data from a filesystem on a RAID array, unless I’m confused about what e2image actually does. Are you trying to use it on the underlying drive devices by any chance? You have to point it at the RAID device on top of them, something like /dev/md1 rather than /dev/sda1.\n
    \n
    This sounds like a good extra backup to have but don’t let it lull you into a false sense of security. It may help recover from a very specific kind of mistake but the recovery may be very specific as well. It’s not file backup.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    May I point out that all a RAID1 does is sync the blocks between two drives. It won’t protect against writing something dumb that would mess up the filesystem, it will just dutifully sync it.\n
    \n
    You *should* be able to back up ext data from a filesystem on a RAID array, unless I’m confused about what e2image actually does. Are you trying to use it on the underlying drive devices by any chance? You have to point it at the RAID device on top of them, something like /dev/md1 rather than /dev/sda1.\n
    \n
    This sounds like a good extra backup to have but don’t let it lull you into a false sense of security. It may help recover from a very specific kind of mistake but the recovery may be very specific as well. It’s not file backup.

    May I point out that all a RAID1 does is sync the blocks between two drives. It won’t protect against writing something dumb that would mess up the filesystem, it will just dutifully sync it.\n

    You *should* be able to back up ext data from a filesystem on a RAID array, unless I’m confused about what e2image actually does. Are you trying to use it on the underlying drive devices by any chance? You have to point it at the RAID device on top of them, something like /dev/md1 rather than /dev/sda1.\n

    This sounds like a good extra backup to have but don’t let it lull you into a false sense of security. It may help recover from a very specific kind of mistake but the recovery may be very specific as well. It’s not file backup.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n

      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      May I point out that all a RAID1 does is sync the blocks between two drives. It won’t protect against writing something dumb that would mess up the filesystem, it will just dutifully sync it.\n
      \n
      You *should* be able to back up ext data from a filesystem on a RAID array, unless I’m confused about what e2image actually does. Are you trying to use it on the underlying drive devices by any chance? You have to point it at the RAID device on top of them, something like /dev/md1 rather than /dev/sda1.\n
      \n
      This sounds like a good extra backup to have but don’t let it lull you into a false sense of security. It may help recover from a very specific kind of mistake but the recovery may be very specific as well. It’s not file backup.

      May I point out that all a RAID1 does is sync the blocks between two drives. It won’t protect against writing something dumb that would mess up the filesystem, it will just dutifully sync it.\n
      \n
      You *should* be able to back up ext data from a filesystem on a RAID array, unless I’m confused about what e2image actually does. Are you trying to use it on the underlying drive devices by any chance? You have to point it at the RAID device on top of them, something like /dev/md1 rather than /dev/sda1.\n
      \n
      This sounds like a good extra backup to have but don’t let it lull you into a false sense of security. It may help recover from a very specific kind of mistake but the recovery may be very specific as well. It’s not file backup.

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Good morning all, in today’s episode of “What I learned during work hours”…\n

      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    The filesystem promptly allocates some blocks and updates the inodes. Maybe the inode table changed, maybe not. Repeat for some other files.

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    \n
    Backups do not solve everything.\n
    \n
    For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
    \n
    Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n

      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      \n
      Backups do not solve everything.\n
      \n
      For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
      \n
      Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

      Backups do not solve everything.\n
      \n
      For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
      \n
      Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Backups do not solve everything.\n

      For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day.

    “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
    \n
    Redundancy is not backup. Read that again.\n
    \n
    Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Backups do not solve everything.\n
      \n
      For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
      \n
      Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

    “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
    \n
    Redundancy is not backup. Read that again.\n
    \n
    Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Backups do not solve everything.\n
      \n
      For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
      \n
      Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

    “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
    \n
    Redundancy is not backup. Read that again.\n
    \n
    Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

        Backups do not solve everything.\n

        For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
        \n
        Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

      “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
      \n
      Redundancy is not backup. Read that again.\n
      \n
      Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        Backups do not solve everything.\n

        For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n

        Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

      “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
      \n
      Redundancy is not backup. Read that again.\n
      \n
      Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        Backups do not solve everything.\n
        \n
        For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
        \n
        Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

      “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
      \n
      Redundancy is not backup. Read that again.\n
      \n
      Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

          Backups do not solve everything.\n
          \n
          For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
          \n
          Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

        “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
        \n
        Redundancy is not backup. Read that again.\n
        \n
        Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

          Backups do not solve everything.\n
          \n
          For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
          \n
          Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

        “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
        \n
        Redundancy is not backup. Read that again.\n
        \n
        Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

          Backups do not solve everything.\n
          \n
          For example once I had a bad cable, and it did a kinda sneaking silent damage. Let’s say 5 or 50 broken files every day. And only after some weeks I noticed some of them, and there was hardly a chance to identify them each day. And sometimes there was damage to the file system, too. It took a while find the root cause.\n
          \n
          Today I use ZFS with redundancy and it does the recovery all by itself and my sleep is so much better :-)

        “Proper backups” imply that you have multiple backups and a backup strategy. That could mean, for instance, that you would do a full backup, then an incremental/differential backup each week and keep one backup for each month. A bad cable would cause you trouble, no doubt, but the impact would be lessened by having multiple backups points spread over months.\n
        \n
        Redundancy is not backup. Read that again.\n
        \n
        Redundancy is important for system resilience, but backup is crucial for continuity. Every filesystem is subject to bugs and ZFS is not special. [Here](https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/)’s an article from a couple of days ago. If you’re comfortable with no backups just because you have redundancy, more power to you. I wouldn’t be.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    +url: null
    +body: """
      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

    Can you enable superblocks after you’ve already formatted the drive?\n

    Fdisk saves the offsets so keeping a record of that at least sounds like a good idea.

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n
      \n
      I couldn’t find any prebuilt solutions for this online, so I wrote a systemd service and timer to do this for me. I save the fdisk to a text file, run e2image on a couple drives, and compress it all together in a dated 7z that can get uploaded via rsync or Mega or Dropbox etc.\n
      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n
      \n
      Unfortunately this does *not* work with my raid drives, but they are RAID1 so already resilient.\n
      \n
      Apparently I was being a derp somehow. …Anyways,\n
      \n
      My RAID drives are 16TB, e2image of this is 125gb, and 7z’d it comes down to just 63mb.\n
      \n
      I’ll post the service, timer, and backup script in a comment, let me know if you can spot anywhere for improvements!

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

      Good morning all, in today’s episode of “What I learned during work hours”…\n
      \n
      I was playing around with wxHexEditor and realised that if something catastrophic happened, I would really struggle with any data recovery if I lost the inode tables for any drive.\n
      \n
      A quick duckle pointed me to e2image, which says in the man:\n
      \n
      > It is a very good idea to create image files for all file systems on a system and save the partition layout (which can be generated using the fdisk -l command) at regular intervals — at boot time, and/or every week or so.\n

      \n
      The metadata image from a 500gb drive is 8gb, but compresses down to 40mb. Backup takes a couple minutes.\n

  +description: """
    From Wikipedia, the free encyclopedia\n
    \n
    Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
    \n
    Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
    \n
    ### Rules\n
    \n
    - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
    - No misinformation\n
    - No NSFW content\n
    - No hate speech, bigotry, etc\n
    \n
