Hi! A friend just recommended the backup tool that comes with Ubuntu. I took a look at it and was wondering what you guys include and exclude from the backups. I just installed wire guard VPN and but the config file in the etc/wireguard folder, where it belongs. I would have to include this folder as well if I want to keep my configs. And I guess many programs do the same, so how do you know what to include, so you can just revert to the last backup if something breaks or you get a new machine? Maybe that is a stupid question, but it was going through my head for some time now. Thanks a lot!

    Does --one-file-system prevent the need for excluding /dev, /sys, etc.?

      Yes but be careful with that option because it depends how it’s implemented by each tool. Some of them will not cross btrfs subvolumes for example.

        Yeah, I think I can see some other funny cases if there’s multiple partitions with separate filesystems on them. Just doing the regular tar/rsync with exclusions is likely safer as it would work for either case.
