I'm running a MacBook with 60GB drive and I would like to keep as much disk space free as possible. I notice that when I do a backup to an identically sized backup disk my backup is smaller than my original. I assume this is because of SD doesn't copy "the temporary and system-specific files that Apple recommends excluding" as it says in the dialog box. I haven't told SD to ignore any folders, I'm using the default settings. On my last backup the amount freed up was almost 5GB.

My questions:

1) What files does SD NOT copy?
Are these log or scratch files that I'll never really need?

2) If the copy frees up disk space, can I copy from my backup onto the MacBook drive with the result that I have a copy with everything I really need and expect but some extra disk space? If I can get 5GB back I'd call that a feature.

Thanks,
Rudy
