Welcome to Android Central! Sorry, but it's not clear where exactly you're seeing this. Which phone do you have? What do you mean by "the Android section where my phone is backed up"? What's the exact message you see? A screenshot might help: http://forums.androidcentral.com/ge...ide-how-post-screenshots-android-central.html.
