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_Serv er/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. .../Ed Disclaimer: I'm a Red Hat Certified Engineer so I obviously have some bias to go along with my experience.
