I just restored my iPhone 5 today (iOS 7) because I needed to get rid of 2gb of buried messages data. So I restored from my iCloud backup. It worked great. Here's what I don't understand. Before I reset the phone, I tried to make an iCloud backup. It said I didn't have enough storage left to do that. So I just said forget it, reset the phone , and when I restored, I used the "restore from iCloud " and it pulled in all my notes, reminders, and email settings. All current. So if iCloud isn't backing up, how is it keeping this data that transferred back onto my iPhone? I really would like to use iCloud to keep my phone backed up, but it shows my storage is just about full.
