You won't get the compressed tarball results directly, but if you are  
open to other suggestions you might find it worthwhile looking at  
rsnapshot.

   http://www.rsnapshot.org/

This approach uses rsync and hard links to provide you with multiple,  
aged snapshots of a remote filesystem; the use of hard links means  
that the only extra disk space used by the multiple snapshots is for  
files that have changed (files that stay the same take up no more  
space).

The individual files aren't compressed using this scheme; however, if  
you can save space retaining multiple backups using hard links on  
unchanged files instead, perhaps that's ok.
