    Hi Everybody,

    I am currently using TIme Machine before I upgrade to a new OS on my macbook pro.

    My macbook pro HD says I have 233GB used, but Time Machine says it is backing up 181GB.

    Why is there a discrepancy? Is there a box I am not checking when backing up? I am obviously not backing up some files. Any explanations and advice to what's happening? :confused:

    Have you checked System Preferences > Time Machine > Options for any excluded folders?

    Yeah, the only thing that's not being back-up is the external HD I am using. Other than that, no exclusions.
