Are ePub documents in iBooks saved in Backup?
I recently did an iOS update from 4 to 7 on an iPad. I did a full Backup of the iPad to iTunes first. After the upgrade, the process asked whether I wanted to restore from a backup, which I did, selecting that backup. The restore appeared to work in all respects except iBooks. The user of the iPad had a large collection of EPUB eBooks, not purchased through iTunes. They all appear to be gone. Was this backed up in the Backup process? Is there a way to recover the data?
iPad, iOS 7.0.3, iBooks Issue
