Microsoft doesn't return any knowledge base articles on how to do a backup, but it's detailed in an article for what to do when what looks like how to do it doesn't work – sort of.

"Method 1
Create a backup with Windows Complete PC Backup. Use the Back up computer option in the Backup and Restore Center.
To do this, follow these steps:
1. Click Start , type backup in the Start Search box, and then click Backup and Restore Center in the Programs list.
2. In the Backup and Restore Center window, click Back up computer.

Note When you run Back up computer the second time and successive times, only an incremental backup image of the computer is created.

Since I don't have Vista to look at, I have to guess that it allows you to do a backup to DVD, assuming you have a DVD burner. You may be able to do an incremental backup to several CDs, but I don't think the bare system will fit on one CD(?).
