I run my containers in an LCX on Proxmox (yes I heard I should use a VM, but it works…)

For data storage (syncthing, jellyfin …) I make volumes in the LXC. But I was wondering if this is the best way?

I started thinking about restoring backups. The docker backups can get quite large with all the user data. I was wondering if a separate “NAS” VM and NFS shares makes more sense. Then restoring/cloning docker lxc would be faster, for troubleshooting. And the user data I could restore separately.

What do you guys do?

    If you’re using LXC and your filesystem is BTRFS you can use the built in snapshots.

      Yes, before doing major changes i usually run a snapshot

      I listened to https://thehomelab.show/ podcast today, and they mentioned that before doing major upgrades, you could create a clone VM from latest backups and test the upgrades before doing them for real. That way you both ensure safe upgrade and also make sure your backup is restorable.

      It sounded like a good idea, but it got me thinking of the size of my LXC filled with user data… So I was wondering if I was doing it wrong

        With BTRFS you can take a snapshot, upgrade and if things go wrong rollback to the snapshot. Snapshot are incremental so you won’t have issues with your data.
