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!
I back up the entirety of my /home directory except for cache, temp, trash (trash is stored at /home/$user/.local/share/Trash), Download folder, and a folder I named “NOBACKUP”.
It backs up a lot of stuff I probably don’t need, but I’d rather back up more than I need, than to be caught not backing up something that I did need.
edit: oh, I have a btrfs snapshot of /root too, but I don’t think that’s something the backup tool in Ubuntu can do since it defaults to ext4
