You connect an external disk (no idea if it works if you have multiple disks in a MacPro ie, you have 2 internal HDDs, both 500GB, and use one to back up the other) and it asks you if you want to use it as a Time Machine drive. You can specify which folders get backed up, and how often.
Also, should your machine need to be reformatted, you can restore from a Time Machine backup. The files are saved to the hard drive in a non-proprietary way, so you can recover them from any machine that can read HFS+.
I am really looking forward to it since it will let me not have to worry about file backups again. "Just set it and Forget it" (C)
