I have a 1 TB backup disk.  I've been using this backup disk for a couple of years.  For the last several months I keep getting a message from Time Machine that it it cannot backup because it needs 519 GB and only 425 GB are available.  Why is it trying to re-save my entire hard drive rather than just updating the changes?

MacBook Pro, OS X Mavericks (10.9.2), Back up disc is a v63600-C 1TB
