I have multiple devices using the 5GB Free iCloud option for documents and game save syncing. I have no backups from IOS devices backed up to iCloud, yet my account says 2.29GB used for Device Backups. I have been to the settings app on both iPhone and iPad, no backups. I have been through preferences on my Macbook, (this should show any backups) it shows none. I'm using 400mb for documents etc and all seems ok with that. I've looked at icloud.com using a browser on my mac and it confirms the 2.29GB used for device backups (shown as a yellow line and named Backup), but nowhere can I see what the backup is of.
