I agree that these comments are more general and not related to SP2 and maybe a new thread to discuss these issues should be opened, however I totally agree with the comments made regarding poor quality control and introduction of new bugs/issues with almost every release. I don't know how a claim of 300+ deployments without incidents could be believed, as this kind of stuff has not been limited to v9 only.
My opinion is that CommVault should stop trying to be all things to all people in the immediate term, stop producting glossy sales brochures that promise the world (and neglect to mention all the associated provisos, exclusions etc) and focus on getting the basics working.
We have raised 13 new support calls in the first week since the v9 upgrade (SP1b) not to mention calls we've had open with v8 for 12 months+. Some of these calls simply indicate thorough testing has not been performed - as does the constant proliferation of patches. I have a list of probably 20 v8 issues that I couldn't be bothered going though the pain of raising calls for as they just disappear into the black hole of "MRs" and don't get traction. I can provide many specific examples.
I understand all backup products have their quirks/issues/limitations and as I've used a number of them and there are some things CommVault does very well, but I have never dealt with such a bug ridden "Enterprise Class" one. Maybe this has just been my experience, or just that other folk running CV have very small or Windows-centric deployments only.
