Not to hijack Jay's thread but I test drove Mozy and Carbonite a week apart.

Mozy was the more fluid of the two, easier to pick up and use.

Here's how it works:
Download and install. Open the interface. Your drives are listed in the left hand pane. Check off each drive you want backed up as well as directories on the C drive, ie: My Documents, ect.
Backup will start immediately or at a your predetermined time. (we choose 3:00am every night).
Drives must be running to backup. We only turn on the drives we want backed up before closing for the day.

Now the downside.
It takes a loooong time to backup each drive the first time.
After that drive is backed up, future backups will included only new files that have appeared, or any files that have been changed. That speeds up the process dramatically.

To retrieve folders, files or entire drives, click "Restore" in the interface. Mozy will ask for a directory to place the files being retrieved.

At $50 a year, it's the deal of the century.
