How to backup Lutris before Steam Deck RMA?

Hello!

I have to RMA my Steam Deck (one of thumbsticks grinds against the plastic case) and I'm trying to backup my non-Steam games (and their Lutris configs).

Apparently Discovery uses flatpak, so Lutris config files aren't where the internet says they are (~/.config/lutris/games/, ~/.config/lutris/system.yml, ~/.local/share/lutris/pga.db).

Could anyone please tell me where I can find these on the Steam Deck and what else I might be missing? I've already backed up ~/Games but I'd rather not have to re-add the games manually :(

Bonus question is if anyone has any tips for painless Steam Deck backup/restore :)

EDIT:

After a long search, I was able to find it. If anyone else is wondering, the Flatpak/Steam Deck Lutris config files are located in ~/.var/app/net.lutris.Lutris/config/lutris.

For some reason, Lutris-installed native Linux games also treat ~/.var/app/net.lutris.Lutris/ as their home folder (e.g. Stardew Valley stores its saves in ~/.var/app/net.lutris.Lutris/.config/StardewValley instead of ~/.config/StardewValley).

If anyone can say why this happens, that would be very appreciated!
