This would keep the backup on the hard drive. Not a good idea in case of
a disk failure. Better to a USB drive.

Wouldn't that dump the entire system into /mnt/restore? 

I'll take this opportunity to reveal my ignorance. Up until now I've
never had to restore an entire system. What would happen if I ran, on a
clean install:

rsync -avz /media/disk/backup /? Would that repopulate the existing
directories or would it install the entire system in /, duplicating the
existing directories?
