I used to use rsync for that kind of job, but nowadays I tend to prefer
`bup` because it handles incrementals really well (especially in terms
of compression). It's in Debian stable or you can find it at
PS: Of course, you'll still want to take a snapshot (e.g. with LVM) and
back that up rather than the live filesystem.
