ipad air backup issues
I purchased an ipad air for my wife and wanted to keep her old purchases. I did a backup of her ipad 2 to the windows computer, then chose to restore to the ipad air. All seems ok except whenever I try to do a backup of the ipad air, it seems to go through the motions, but always finishes with the message that no backup has been done under the last backup information. I don't want to lose the work that she is doing on the ipad air, but I have tried several things and cannot get it to show a backup has been done.
iPad Air, iOS 8.4, itunes on windows 7 pro pc
