Ok, here's my problem, recently I haven't been able to backup. Why this is? Not too sure...I don't remember changing any settings or anything recently but within the last 2 weeks or so I haven't been able to backup at all. When I start backing up it says "preparing backup" then an error message pops up that says "The backup disk image could not be mounted". I have no idea what to do or how to fix this? ANY ideas would be greatly appreciated.
