Great idea Paul!  The bulk of the data is going to be shared out to a single 
NFS server.  So the plan was to test NFS --> Linux Server --> Media.  If I can 
remember correctly, making that Media server a SAN media server would only run 
$2500 or so which is about 25% the cost of NDMP.  We're a mixed Windows / Linux 
/ Solaris environment.

I'm unsure where the Linux box comes into play.

If the appliance presents an NFS share, and you're going to back the appliance 
up via NFS, at the very least, I would mount the share ON one of your (*nix) 
Netbackup servers.
If I were adding in a net new linux box to mount the share, (just because you 
want another server, or because your existing Netbackup servers are all 
windows) then I would be making that linux box a media server.

Otherwise, if you're mounting the share on the linux box, then backing up that 
linux box as a normal network client, then you're passing the data over the 
network twice...once from the NFS server, to the linux NFS client, then from 
the linux client to the media server.

If you're gonna make a net new linux box a media server (a SAN media server at 
the very least), it'd probably be cheaper to just buy the NDMP licence.

If you have an "all windows" Netbackup inf. now, then it's probably not going 
to be up to the task of being a decent NFS client with any sort of throughput 
performance.
