Yea, after spending all that time getting your system config files just the way you need them, it would be a real pisser to have to do it again just for lack of a backup
Along with full system backups, I keep a handwritten log book that tracks all system changes made as root in case of a real proper disaster
That way I can at least retrace my steps. Makes it easier to remember stuff when trying to help a fellow *nix'r as well.
