I would use Acronis True Image, but there is no need to backup to DVD, Acronis makes it's own secure partion within your C: drive and can be restored by hitting F11 on boot. No problems, I would not be without it. click here
I would also recommend Nero, just burn a DVD instead of a CD in the same way and it'll be fine. As in the case of photos to CD recommend making 2 copies and checking them every month or two months and if theres a disk fault immediatly make another backup. Nothing worse than losing your prized photos cos the disk has a fault or the disk gets dropped and scored or chipped on the edge of a coffee table or something.
