We have the same library as you. We have also wanted to use native NDMP 
for our filers, but are waiting for the "file level backup/restore" holy grail. 
Up to this point, we are backing them up over NFS. Not the most efficient, but 
it works as we have a "beefy isolated dedicated network" for backup traffic.

        I floated the same question out here a few months back and heard 
nothing. In reading the documents, it sounded like you used to need to attach a 
local tape drive to the NetApp, but in recent versions, it talks about 
configuring a "path" to the drive and using the drives already defined to TSM. 
But then the NDMP backup is still being funneled through the TSM server to get 
to the drive, right?

        From the documents I read, it sounds like to get it to work with the 
data flowing directly to the tape drives, your TSM server has to be part of a 
SAN. Ours is not part of a SAN, so I'm not sure how we would hook our NetApps 
to our TSM server to gain the benefits of NDMP.

Subject: 3494/3590 and NAS backups


I'm just curious to know if anybody has any experience with NAS
backups via the NDMP module. In particular, I'd like to know of
anybody working in an environment that has fiber-attached 3590s
in a 3494 library.

The TSM Administrator's Guide discusses these setups in Chapter 6,
but it only mentions using SCSI libraries, not libraries of type
349X. Just curious to know if it's possible (which I'm sure it
*must* be), and to know if anybody has trod down this path. We're
anxiously awaiting the release of 5.2 for file-level
backup/restore via NDMP, and so we are beginning the preparatory
steps for that.

Thanks.
