How to manually backup saves on Xbox app for pc

I’m wondering how (or if its even possible) to manually back up your save files if you own the game through the Xbox app for pc. I recently encountered the dreaded corrupted save and lost all my progress (all main and most side quests done, all exp ammo types, at least 2 of every exp weapon etc.) and am stuck having to restart from scratch. I’m not too upset as I recently found out that making a new character doesn’t reset your quests when I tried to play with a friend who recently started playing through game pass but I wanted to know how to make sure this doesn’t happen again.
