Rsync to a Remote NAS

Oh, the rsync itself will do incremental, however if the filesystem 
below is going over VPN it won't work fast. rsync's design expects local 
and fast filesystems, direct HDD oder via direct LAN, and not mounted 
over VPN.

"readynas" says nothing to me.
Maybe it can play a rsync daemon, but it reads like it could backup 
itself via rsync to a remote location. You need an rsync daemon on the 
other side to receive the data or get the data from. If the other side 
is a "real" server and not just a NAS it should be easy, rsync is avail 
on nearly all existing OS-es (well, limited to those with network 
capabilities).

Maybe it is the smb://xx.xx.xx.xx/whatever that is breaking it......the bottom line is i need to copy/rsync a directory to a remote server through a VPN. How is this accomplished?
