To All -
I concur with Bob. We have over 9 TB of NAS installed, and NONE of it is
mission critical data, which your NBU index data most certainly is. They
make good file servers. Period. The backup/restore options are miserable,
and if you're using an NFS mount for saving your indexes, you are now
dependent on the network behaving reliably, as well as the NAS. In addition,
I'm assuming you're backing up your databases from the Master server on
which they are mounted, which means that if you have a network failure or
timeout during the NBU DB backup, you didn't get your very important
database off to tape, for DRP purposes.
Keep your NBU index disk local to the master server (or on a SAN, which does
NOT rely on traditional network connectivity) - use VxFS and VM to grow file
systems as needed, and quit risking your backups like that - ALL of you!!

Subject: RE: [Veritas-bu] Netbackup DB Catalog File Paths
NAS is just Network Attached storage, and unless your doing SCSI over IP,
your doing NFS. And in either case, all network issues are in place. I'm
not a big fan of NFS or NAS in any mission critical application, like ERP,
Databases or in a fail over system, and especially for managing NBU
catalogs. Disk is cheap, and if you use VERITAS Volume Manager and File
System you can grow volumes and file systems on the fly.
NAS is great for file services and sharing information that many people need
direct access to, which is not the case in any of the applications I
mentioned above.
NAS and NFS is subject to network problems, and direct attached SCSI is much
more stable.
This is my opinion and not to be mistaken with a VERITAS point of view,
Thanks,
Bob

It works fine, but NFS is not a technology that offers "guaranteed
uptime." That is not really in Veritas's hands, and they're not urging
anyone to use NFS for this.
My question is whether NAS is stable enough---whether NAS offers an
additional stablility to NFS that gives enough of a guarantee to use for the
NBU databases.

I'm not using a NFS but I have mounted my NBU catalogs and files as a local
file system and have successfully grown it using Veritas Volume Manager
without any problem. I think, conceptually, you should be able to do it.
After all, isn't that the underlying basis for NAS and SAN? I would find it
peculiar that Veritas didn't support it with their own products. But hey ...
I've been misguided lots of times in my life.

Hello
Have you had any experiences with storing NB Catalogs
on an NFS Filesystems ? I am trying to find out if they
are problematic. Our netbackup catalog size is ever
increasing due to our increasing backup tasks
and I am thinking of throwing a part of it on a Netapp
filer so that I can grow it on demand..
(or I could add an internal disk, but that's only migrating
the problem to a future time...)
I appreciate your inputs.
Thanks
Rajeev
