I feel that it doesn't make sense to roll your own, so we recently deployed
rsnapshot, which is a perl script that wraps around rsync and uses hard links
to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals.

So far its running on roughly 400 servers and we have not had any issues other
then running out of inodes on our backup device ;)
