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 auto-backup my entire /home, except for stuff I explicitly exclude and hidden files. I only explicitly include some of the latter, because I don’t want to back up all the stuff programs put there without my knowledge.
Config files outside of /home I copy semi-manually to and from a dedicated dir in which I replicate exactly where they go in my actual FS. I have written shell functions that easily allow me to backup and restore stuff from there and it’s synced to my cloud storage.
