You might be better off having proxy systems access the NAS contents using CIFS
and/or NFS, and having the proxy systems use the backup/archive client to back
up the NAS contents.
My department supports Commvault as well as TSM (the result of a merger of
previously separate IT organizations). The Commvault workload includes a NAS
server on the same scale as yours. Our Commvault representative advised us to
forget about Commvault's NDMP support and use the Commvault analog of the
approach described in the previous paragraph.
The subject of NAS backup coverage arose at an IBM training/marketing event for
the Spectrum family of products. The IBM representative who responded was not
as bluntly dismissive of NDMP as our Commvault representative, but he sounded
decidedly unenthusiastic when he mentioned NDMP as a possible approach to NAS
backups.

Hi all,
I’m working on a large TSM implementation for a customer who also has HDS NAS
systems, and quite some data in those systems, more than 100 TB that needs to
be backed up. We were planning to go 100% directory container for the new
environment, but alas IBM’s “best of both worlds" (DISK & FILE) doesn’t support
NDMP and I don’t like FILE with deduplication (too much of a hassle), so is it
really true, are we really stuck with tape? ISn’t it about time after so many
years that IBM finally gives us a decent solution to backup NAS systems?
