I can't quite parse that last sentence...

Why use CIFS? Netapp understands NFS like no one else... so use NFS!

Using rsync over a "network drive" isn't that useful, rsync is meant to
optimize network traffic between de sender and the receiver, possibly at
the cost of more disk IO. In this case, disk IO on the sender *is*
network traffic...

Use -v (one or more times) to see exactly what's going on.
