WHY you should keep good backups...

[TurcoLoco]

Yup. My Windows partition is about 15GB and my programs partition is pushing 120GB and my third "stuff" paritition is another 25GB...

Hahaha, you refer to your entire partitions as "data", hahaha...silly boy! Why are you backing up programs and the OS that you could re-install from the CD, DVD, etc.?
I only save configuration or application data(base) plus my personal sh.t (MP3s, documents, pictures), after all that is all you really need.
