If you want to backup gigs and gigs of your entire system CDs and DVDs are really not an efficient way to do it.
The software is not the problem as Microsoft provides its own backup utility, Ghost is good (for an image), so is Norton Go Back, and so is the Dantz Retrospect utility.
The problem exists as to what media you want to use.
There are tape backups used and also external (or even internal slave drives), and these remain the most cost effective and most efficient way to backup.
With MS and Dantz you can do "incremental" backups that just backups what has changed (what data has been added since the last backup).
External hads have become cheap as late - just look at the ads - and you should be able to get an 80gig External drive combo that comes with backup software for less then $100. I did.
