Depends on how much money you want to throw at your
setup I guess. =)
Most of our large catalogs are quite happy living on
the SAN. Of course, our SAN is DMX3s, dual-pathed to separate fabrics and
switches, and runs to two different physical HBAs on the servers themselves.
Even if you're looking at only a single path though,
having your catalog on a SAN volume means you're probably getting automatic
hardware RAID of some level. That's generally a little harder to pull off using
local disks and still have any reasonable amount of usable space leftover.
Plus, leaving it on the SAN gives you the option to do
frame-based replication, snapshots, BCVs, etc etc etc.
But only if you can afford it. =)

All,
Just a general query on the best practice for the location
of the NetBackup catalog (Its DB, images, ect).
When you install NBU on a Server, the
location can be accepted as the "default" or you can customise the installation
and choose an alternative location (ie: Spare drive on local server, SAN
attached drive, ect).
Presently, I have NetBackup and the
catalog installed locally, on RAID5 set, hot swappable.
My question is this: Is there a best
practice for the location of the Catalog? For example, SAN attached disk? I sort
of feel uncomfortable with this for several reasons:
1) If you lose SAN connectivity (due to
a major disaster or failure) the catalog has gone
2) NetBackup and the OS relies on that disk being available
constantly
Being stored locally, means the Server
and its application (including the catalog) goes with it, and does not rely on
an extra layer of hardware for the catalog to be available.
I think my concerns come from a
previous environment where the catalog was stored on a SAN, and was
totally destroyed and unrecoverable, which meant a complete import of hundreds
of tapes.
If anyone has any feedback on this,
would like to hear the pro's and con's to storage off the physical server
itself. I have always had the catalog locally stored.
Thanks,
Simon
