I am trying to back up my computer with Time Machine and everytime I select "Back up Now" I get this error message:


"This backup is too large for the backup volume. The backup requires 163.3 GB but only 148.2 GB are available"


However, I am only using 136.14 GB total on the Macintosh HD so 148.2 GB should be enough. Why is it telling me the backup requires 163.3 GB when I'm only using 136.14 GB?


What could be the problem here?


I am running OS X 10.5.8


Thank you!
