Prabal DevOh! Google Photos already does this since years! And why do you use OneDrive for things like "pics" (which are different from documents/files that you might keep in OneDrive) ?
Jan-Lukas ElseOneDrive does this for years already as well! I use OneDrive because I have a Microsoft 365 Family subscription and keep almost all my files in there, including photos. The Android app backs them up automatically.
tzinmInteresting! I use Photo Flashback, although it’s not the same because is limited to iOS and the photos taken with that device.
