I have a program at home to ghost my system drives to DVD and a backup HD. I have a clean install disc, another with my programs installed and then a few regular backups. Symantec bought them out years ago and they offer
Norton Ghost and the slightly cheaper
Norton Save & Restore. It's great being able to just toss a disc in, after replacing a faulty hard drive or just starting with a clean install, and being up and ready in about 10-15 minutes.
