I have a free 5GB account, so the last successful back up was in October (when this jump occurred). I didn't change anything on my end around that time and the timeframe doesn't necessarily line up with an iOS update. The largest single app backup amount is Minecraft at around 100MB. I don't use my iPad as a camera so the Camera Roll is negligible. Based on searching other forums, I've tried the following thus far: 1. Turning off / deleting backup and turning back on 2. Backing up to MacBook then trying iCloud again 3. Turning Camera Roll backup off and then on (strangely, I could not keep it off - it automatically turned back on once I turned it off) None of these were successful. Any tips?
