My experience has been this with NFS and CIFS (hosted on a EMC Celerra). NFS 
mounted filesystems backup fine when done via a Unix or Linux client they are 
mounted on. Speed seems to depend on your overall network throughput 
capabilities. CIFS on the other hand can be a problem as they only seem to be 
mounted by Windows for an active login session and are not normally permanently 
available to all users / processes of the Windows server client unless they are 
somehow mapped to a permanent drive partition each and every boot time (don't 
know if this is possible as I am a Unix weenie). I would suggest backing them 
up from the machine that hosts the storage somehow if it is a supported 
client... 
I am not aware of any 'tuning' capability within Networker to adjust the 
performance, what you get is what you get...
