I using Sync back to back up my Documents (minus my music and video files) to my other drive. (not sure if I use RAID or not...)

Anyhow that little lot gets backed upto CD every week ish.

My music is bit harder...now all my documents and most of my programs (deliberatly run as no registry programs so I can reformat and straight away use them on a new PC :D) are also stored on a 60Gb laptop drive in caddy.

Music and video sometimes backed up to DVD... :?
