In this case, since both drives are local, rsync is the same as cp -a 
(it uses a different syntax, which might make it easier to get a more 
sophisticated data set).  Unless you go through the effort to set up a 
system that only copies changed files.

But that's what rdiff-backup does, so use it.  As for removing old 
backups, when you do your backups run it with "remove backups older than 
X" and then run it with "do the new backup".
