I mod my games on my PC and sync it to my SteamDeck. I also sync the save files back and fourth, to continue playing on different devices. Mostly non-steam games.

I also sync my eBook collection to my eink reader with syncthing.

Everything is also mirrored to my always-on NAS, so syncing always works.

I am hosting bitwarden myself (on a VPS) and I am not that concered about losing my passwords, because every device syncs all passwords locally regulary so that you don’t need internet to access them.

So to loose all your passwords not only do you have to loose your bitwarden server and all the backups, you also have to loose access to all your bitwarden clients synchroniously.
