You should always make a backup before you mod. Saves your scores and downloads so you can quickly change back to live to play the latest official soundtracks or song packs from Beat Saber.
Or a modded Beat Saber backup allows you to get back to the thousands of free songs in case a brother, sister, friend, cousin, or nephew jumps on the head set and clicks restore.
This guide goes over how to make the back ups for modded and live beat saber. The process takes 5 minutes to set up and only 1 minute to swap from mod to live or live to mod.
