Hello,
Please take a look at rsnapshot http://www.rsnapshot.org/.

It should be able todo what you want, and more. It uses rsync. The first time 
it runs it will take some time cause it needs to copy the whole thing, but 
after that it will just copy the differences in file, so if you have nothing 
changed it'd really fast. I've been using it to backup user data and 
configuration files from our servers (about 300 GB data from 4 different 
machines) to sync every 6 hours, and have been happy with it.

HTH.
