rsnapshot does that for you, using rsync and hard links.

Sure, these convenient wrappers around rsync handle some common cases
with less work. But they still don’t offer the full power and
generality of rsync itself.

Also, rsnapshot refers to this article
<http://www.mikerubel.org/computers/rsync_snapshots/>, which has been
obsoleted by the addition of --link-dest to rsync. Does rsnapshot make
use of that to simplify things?
