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 ☺️
I use syncthing to backup files to a different device
Alternative, for windows, solid for years.
not open source, unfortunately.
I’m a vegan.
Best way to do this is to just find your save file location , and make your own backups…
You don’t need some program to scan your system for you.
Doing this every few minutes is annoying af. Wanted a tool like this for ages.
