rsync - Jun 2009 - which server to make client and which the server for rsync.

I am using rsync to keep a mirror of my 800GB /home (server1). The
backup machine is a separate server (servr2). Currently I am running
rsync daemon on server2 and invoking rsync daily via cron on server2.

Are there design / performance considerations that influence which
machine is made the server and which the client?

Also, Is the rsync daemon the preferred way to o this backup? I can
also cross mount via nfs. Would that help or worsen my performance?

The NFS mechanism I've found to be slower than the rsyncd method.
Another to consider might be the ssh/rsh, but then the ssh might impact the
transfer speeds.

My rsync processes typically are wrapped in a script that performs
other tasks on the backup server, so I like to pull my data down to
the backup server.  Basically if you need to do any processes after or
before the rsync, it is nice to have the script run on the backup
server.

always.
