Re: rsync

 I use rsnapshot to back up a bunch of servers and desktops. 
Several of the servers run CentOS 4.5, and it would be nice 
if rsync's link option could recognize and deduplicate the 
identical files from separate machines. 

Another nice feature would be for rsync to recognize when 
renamed or relocated files happen to be identical, too.
