rsync can run as a daemon on the box that you want to store or retrieve 
files from, by issuing "rsync --daemon" google "rsync server setup".

But to answer your question, NO rsync does not automatically back things 
up, it's a utility that you can write a script around, and schedule. 
There is one I've been playing with called "Snapback", go to 
search.cpan.org and search for "snapback".

As far a different versions of rsync playing well together, my guess is 
yes, as long as you use the common set of options and functionality 
between the two versions.  Someone will correct me if I'm wrong
