Oh you’re right it does work… well fuck knows what I was doing wrong before.

Yeah this is a backup in case I like, mv file to /dev/sda1 or something.

Not a backup of the files, but a backup of the structure.

Ok time to investigate ZFS

For fun and learning. It’s just another tool to go with file level backup.

And the backup for this is 40mb and really fast, but backing up files even when compressed would be hundreds of GB, maybe terabytes, and then you’re paying for that amount of storage online somewhere, uploading for hours…

Great tips, thanks!

I’m using ext4 across everything I think.

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

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

The script takes the drives as arguments:

Set to run at 3:40am every day, but probably could be once weekly really.

Should be fairly self-explanatory.

ISPs still have data caps?

That should be outlawed by now.

I needed a way to pass an argument into the command so it can be used in name=“$1”

luthis, 1 year ago to linux in How to take actions on multiple docker containers at once

Dude, I use the CLI all day, every day and I can’t freakin remember half the commands I need.

If it’s something I use often, I’ll make an alias even if it’s just so I can run ‘alias’ in the terminal to get a list of things I use often.
