I have Syncthing installed via pacman (since flatpaks cannot keep a daemon running). For every game that I care about, I find its save file, move it to a sync dir, and symlink it back to where it is expected. My savegame sync folder has folders for the many varied places that games like to hide their saves - “gamedir”, local, locallow, “my documents”, dot_config, etc. The most fun part is finding out where the appropriate proton prefix is.
If I was starting over again, there’s a decky loader plugin that looks promising.
I have the same setup, but I am using the flatpak version of syncthing. It can run a daemon just fine, however I am running a user systems service. Works great and starts automatically in both desktop and game modes
Syncthing and/or Warpinator.
By exclusively playing on Steam Deck there is no need to sync anything ;)
There’s a decky extension that will automatically backup game saves to various cloud storage types.
Oh I love decky. I’d love something automated that doesn’t need me to go into desktop mode so I’ll look for that.
I haven’t done this for game saves but you could probably use syncthing for this.
I use syncthing for automatic transfer of emulation saves. It’s pretty fantastic
I moved a Jubilee save from my Windows desktop to the Steam Deck once.
Never again. It’s a hassle. I ended up only playing it on the Steam Deck henceforth.
Depends. Many games from Epic have that built in. For everything else I use Nextcloud. I think most people use Syncthing.
