Sanity check - is rsyncing to a remote computer that has zfs snapshotting an okay way to back things up?

I currently have two computers, one that has a big zfs raidz pool that I currently back everything up to. Right now, on my local computer I use rsnapshot to do snapshot backups via rsync to the remote zfs pool. I know I’m wasting a ton of space because I have snapshotting in the rsync backup, and then the zfs pool is...

Using plain rsync sounds sane.

Sending local ZFS snapshots to the remote ZFS might be problematic. Consider accidentally deleting important data locally and nuking all of your local snapshots, then sending that to the remote ZFS. You lost all of your snapshots and there’s no way to recover the deleted data. Instead do what I do - keep the two ZFS systems separate and use a non-ZFS mechanism to transfer data - rsync, Syncthing, etc. That way even if you delete everything locally, nuke all local snapshots and send the deletions via rsync remotely, you could still recover your data by restoring the remote ZFS to a snapshot prior to the deletions. For reference I have two ZFS machines doing frequent snapshots and Syncthing replicating data between them on immediate basis.

!selfhosted, please do critique if you find some fundamental issues with this.

Cause it makes sense at a glance and it’s efficient. Not for backup purposes though.

Wouldn’t send/receive also sync snapshots across ZFS instances?

What’s the WiFi adapter?

Here’s how the trigger could look like:

Another happy Framework user here. I have 2 first gens in my immediate family and 2 second gens among my friends. All run Ubuntu LTS. No one is complaining. I’ve already replaced my bottom chassis because I destroyed it during a bad mishap. Ordering was easy, the part was inexpensive, the replacement was straightforward. A Dell XPS perhaps feels a bit better made, but then it doesn’t say Made in Taiwan on the bottom so there’s that. 😅

On the other hand System76 is building a new open source desktop environment in a sane programming language… 🤔 If COSMIC desktop turns out great and I end up using it, I’ll probably throw a couple of hundred their way in lieu of buy their laptop.

Oh I now remembered that mine developed a problem with one of the USB ports, not a cartridge but the host port. Framework sent me a new board. I replaced it easily and sent the bad one to them.

Always, as others have said.

Finally doing what they should have done ages ago. If you leave packaging and backporting work to distro maintainers, you’ll get whatever they have the time for, whether they’re volunteers or employees. If the results are not okay for you - package it yourself.

What's (are) the funniest/stupidest way(s) you've broken your linux setup?

Tinkering is all fun and games, until it’s 4 am, your vision is blurry, and thinking straight becomes a non-option, or perhaps you just get overly confident, type something and press enter before considering the consequences of the command you’re about to execute… And then all you have is a kernel panic and one thought...

Tried to convert Ubuntu to Debian by replacing the repos in sources.list and apt dist-upgrading. 💣 Teenagers…

An intern nuked their workstation by sudo chmod -R 777 /. Turns out adding exec to everything isn’t good either.

Second that. VM suspension is but the only way to achieve this on a standard OS.

Sorry, why are we switching away from Plex because of this? Genuinely asking.

E: Wow at the downvotes to an honest question. 🥲

avidamoeba,
@avidamoeba@lemmy.ca avatar

Thanks. I understand this perspective.

Is that bad though? I don’t mind renting a movie I really like even if my friend has it on their Plex. Especially if it’s from a small studio. Currently I do that via Google TV. Plex Inc being a small private company might use the money better than a publicly traded giant. I wouldn’t mind my friends and family spending a few bucks on it either.

Of course if Plex starts enshitifying existing private streaming features to push this, that’ll be another matter altogether. Which would not be unexpected.

I’ll probably trial Jellyfin too in preparation to migrate the family should push come to shove.

Recently received an AirGradient One. Added it to HA via ESPHome. The setup was pretty smooth. It shows the following sensors in HA:

  • CO2
  • Humidity
  • NOx Index
  • PM 0.3
  • PM 1.0
  • PM 10.0
  • PM 2.5
  • PM 2.5 AQI
  • Temperature
  • VOC Index

Memes are cool. Blatant misinformation in the form of a meme to manufacture outrage, not so much.

@avidamoeba@lemmy.ca avatar

Even though this has been explained many times since the whole hullabaloo, I’ll assume you’re genuinely unaware and/or perhaps got rage-farmed by someone else’s meme. The current meme implies that Ubuntu/Canonical have actively disabled safety/security features in the form of withholding security updates, unless you pay for Ubuntu Pro subscription. The Ubuntu package support hasn’t changed with the introduction of Ubuntu Pro. The packages that were supported by Canonical prior to this are supported the same way today. The packages that were community supported prior to this are supported the same way today. Without Ununtu Pro. There is net new support by Canonical that covers community-supported packages too which is available with Ubuntu Pro subscription. Therefore Canonical hasn’t removed any existing, previously free security support. In addition, this newly added security support is available for free for up to 5 machines and it lasts for 10 years.

Don’t need to. It’s useful while free for people who wouldn’t otherwise pay for it. If/when we get the rug pulled from under us, mothrrship Debian is right there.
