I have a test 6.5.6. master running on CentOS. Simmilar to Jeff’s
scenario, I had to drop a “real” redhat version file into /usr/openv/netbackup
before some of the patches would install, but it runs now without issue. This
is not production, but it does work just fine.
As far as CentOS in the datacenter, two of our most recent acquisitions
run CentOS exclusively. As with most decisions, I assume they examined their
options, balanced the risks and rewards, and made an educated decision. Neither
ran NetBackup (before I deployed our standard Windows master.)

As to not running on CentOS – The only thing I know of off
the top of my head that blows up on install is Oracle products but that is
simply because they put a routine in that tells it which OSes they’re
allowed to run on. You can certainly run Oracle products on CentOS
(unsupported by Oracle of course) by simply tweaking the file that stores which
OSes are allowed OR by modifying the /etc/redhat-release file to make it say it
is one of the supported RedHat versions.
Of course in my post I did also say that running CentOS as your
master server is a bad idea even if you could make it run due to support
issues.
I’d disagree with what you say about the release cycle of
CentOS – since its releases are tied to RHEL’s it has the same
release cycle (delayed somewhat). However, I’m not suggesting
it should be supported by Symantec or any other vendor.
Here we run RHEL for 95% of our Linux needs (and 100% of our
Production Linux needs). We have CentOS and Debian installs for
very specific one off systems or workstations. It is fine to say to
the user “it might work, but it will be unsupported” but to try to
pretend there is some inherent badness in other distros as opposed to RHEL
isn’t appropriate in my view. I know of one Atlanta based
cable network that runs Ubuntu/MySQL for most of what they do in the Linux
arena (including web servers) where they formerly ran HP-UX (UNIX). The
folks there wouldn’t be caught dead running RHEL or any RPM based distro.

Not tested. To compile and maintain the client code is a
relatively simple process; to compile / test / qualify all of the media and
master server functionality is a huge undertaking.
It’s not just a matter of “compile it and see if it
runs”. You have to test all of the supported peripherals such as robots,
tape drives, storage arrays, etc. and then try to maintain this on a platform
that is built by a group of volunteers around the world making who know’s
what changes?
People such as Redhat and SusE have very well defined hardware
qualification plans and detailed release cycles; this is just not the case with
CentOS.
Add to this that there are relatively few people who use CentOS
in a datacentre environment (compared to Redhat or SuSE that is) and it quickly
becomes commercially unviable.

Intended - yes
In practice - mostly
There are cases out there where applications intended to run on a RHEL distro
will not install without modifications. The distributions, although based
on the same sources, are not the same. There are applications out there
TODAY that won't install or run correctly on CentOS but will install and run
correctly on RHEL.
RHEL is not self-hosting - in other words, it's possible that the binaries you
get can not be built with the sources you get. That's happened in the
past due to compiler bugs but I haven't heard of it happening lately.
CentOS, as a client, is supported by Symantec according to the current
compatibility list at ftp://exftpp.symantec.com/pub/support/products/NetBackup_Enterprise_Server/337048.pdf.
It's not supported as a master or media server. We don't know if it's
because they tested it and it failed, or if they tested it, it worked but they
don't want to support it, or they simply didn't test it.
In general, I would expect that you could make a NBU 7 master install on CentOS
and it would likely work. It will not be supported by anybody.
Depending on the tier of the hardware that you're running the master server on,
the list price for the x86-based Linux master/media runs from $5K to $12K and
that doesn't cover any clients or options nor the backup hardware or
media. A RHEL subscription can be had for $349 per year.
My personal opinion is that the $349 per year should not break the business
case.
