Not exactly sure what you mean by "new rsync features", but I wrote the 
following script a while back with a similar purpose in mind and have 
recently updated it:

https://lauren.room52.net/svn/lstewart/misc/scripts/rolling_backups/trunk/

Username/password: guest/guest

It still needs a little bit of polishing, particularly the stats 
reporting feature, but works as is. The configure script is currently 
redundant and you can simply rename "backup.sh.in" to "backup.sh" and 
make it executable. The usage statement and comments at the top of the 
script describe how to use it.

I use it to do all my home and non realtime-critical backups, but YMMV.

Cheers,
Lawrence
