Yep.
>From Windows you can use a CIFS share, or from Unix an NFS share.
TSM Windows services have to run under a network account, not a local account,
but that's easily fixed.
Then your DEFINE VOLUME commands (from Windows) just use UNC names instead of
X:\ local drive names, like this:
define volume stgpool_name \\nashostname\sharename\vol1.00.whatever
formatsize=nnnnnMB
BE CAREFUL about how you set up the nashostname\sharename, once it's done you
can't change it in TSM.
And if it's CIFS, remember you are going from the TSM server across your
network via TCP/IP to get to those storage volumes, and it will be slower than
SAN storage attached via HBA (unless you are using 10GE and a very fast NAS).
In my experience I usually find that writing to the share gets some I/O errors
due to Windows timeouts from CIFS delays. If so you will need to go in the
Windows registry and increase the timeout allowances for CIFS to stop the
errors.
Make sure your TSM server is on the same network segment as your NAS - not
going across something like a distributed switch or a firewall. (And consider
maybe using it as a second tier of storage - do your backup clients to fast
disk, do your backup stgpool from there, then migrate out to the slower NAS
storage for long-term. Otherwise you could be writing the data from the
client across the network to the TSM server, which writes it across the network
to the NAS storage, then you pull it back across the network again to do BACKUP
STGPOOL to tape. Will your network be a problem -- or will you be the network
problem -- in that scenario?) And all NAS devices are not created equal - some
are fast, some are dirt slow. Will yours support the I/O rate you need for
TSM? And how many times will you be moving the data to/from it?
But it works. You just need reasonable expectations and some tuning. Start
slowly and test.

Subject: [ADSM-L] NAS storage
Can NAS storage be used to back up data? Can I set up a storage pool on the
TSM server to back up to NAS like I do SAN?
Thanks,
Eric
