This problem is killing me! I have tried all the suggestions of deleting the old backup files, removing possible trouble apps, uninstalled and reinstalled iTunes, etc, etc.
I have no idea why this is so crappy -- and why Apple is refusing to acknowledge the problem. I've looked even in the Apple forums and people are talking about the problem, but no response from Apple.
It's killing me now because I want to upgrade to iOS 4.2 and the upgrade forces the system to run a backup first. So i am never getting to the actual upgrade because the backup has been taking so long!
Anybody have any other solutions??
BTW, I have an iPad 3G 64GB, but memory is less than half full with mostly music, video, and photos.
