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!
An OS can be restored. Backup your data, so
/homefor sure and maybe any custom configs for/etc, like your wireguard configs. So anything you specifically edited/added for/etcdirectory.Skipping the OS backup is reasonable, but you probably want to at least save a package list. Add something like
dpkg -l > ~/packages.txtto your backup script.
