iCloud backup won't complete
Camera Roll is gone in iOS8.  

It might be that you would nee the new iCloud Photo Library, part of iCloud Drive, before they will sync again.

One thing to do is to migrate any photos you might still have in iPhoto - launch it &amp; you will be given the option - as that's gone too.
