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.

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? -- Met vriendelijke groeten/Kind Regards, Remco Post [email protected] +31 6 248 21 622 The information contained in this transmission contains privileged and confidential information.
