Time machine not backing up for macbook? Help!

[APPLEFAN8]

I go to back it up and it has said preparing back up for the past 10 mins up at the top. Before it would only take a few seconds i'm not sure why it is taking so long. Anyone have any ideas to fix it? Nevermind it is now backing up 3.1 more GB. Thought it was working lol

Sometimes it just takes a LONG time to prep the backup, especially when one hasn't been done for a while.
