I have 2 iPhones and 1 iPad backing up to iCloud. The size of the backups has exploded from around 300-500MB each to 1.3GB recently. I've tried turning off and deleting the backups. The size goes down but it's back up the next day. I also tried backing up the iPad to iTunes and restoring from the iTunes backup. After turning on iCloud backup it grew to 1.3 GB again. Please tell me there is another option besides setting up as a new device. What a pain to set everything up again.
