I want to mirror my micro SD card and my internal storage of my Android phone, as a form of redundancy (obviously not real-time, more of a once-a-day thing), in case my internal storage ever gets corrupt (ex. can no longer boot, but the data is fine). I’ve tried looking for programs which can do it, but nothing appears to do so.
Preferably the app be open source (from f-droid, Github, etc), but if it is on the Google Play Store, that is fine.
Mirroring app data (with and without root, if possible) would also be amazing
