After too much time spent on google I finally found this lightweight GUI + CLI tool that finds locally installed games (yes including non-steam games running under proton) and thought I’d spread the gospel!
Combeined with something like dropbox/onedrive/nextcloud, or rsync/borg/syncthing etc you’ve got yourself cloud backups too.
Zero configuration involved so far on my Steam Deck which is nice as well.
Forgive me if it’s old news ☺️

@Puzzle_Sluts_4Ever @V0lD personally, I use systemd timers, in combination with the btrfs tooling to backup certain snapshots of my filesystem, which include game saves. I can’t use steam because it’s entirely screenreader inaccessible, so I play stuff with retroarch and other emulators, plus the occasional audiogame in wine, and very rarely, native ones, those are so rare.
