• Don't ever trust this Avamar crap to backing up a MSCS cluster with the SQL plug in. first day i had it installed just for testing, it took down the 2008 r2 cluster (failed the cluster over and over and over till the nostart policy i had configured stopped the process), took several hours to fix it. Next having thought i went thru every sql server to make sure it was removed, missed the Biztalk cluster. it corrupted several databases on my Biztalk cluster , including master and MSDB. what a mess, and totally pissed me off.
