Keep a spare root partition on another disk. If both disks (real root and
spare root) have the same geometry, and you allocated identically sized
root filesystems, you can dd the live root partition to the spare from
cron. If they aren't the same size you would need to keep the spare
mounted and do a 'dump ... | restore ...' instead.
Alternatively, forgo all the cron-based sync magic (which *is* a bit
dodgy when you're copying a live filesystem) and just manually sync the
spare root to the real root whenever you make significant changes (new
kernel, password file updates, etc).
