Currently, we have a SQL cluster running on HDS array with Commvault backup.  The SQL cluster is virtual servers in VMware.  When backup of SQL starts, it will use HDS replication manager to take a clone of the SQL luns on the array with SQL VSS quiescing at the same time.  Then, those luns will be presented to another media server (proxy host) to back them up.  That way, the production will not be affected.  We also clone existing lun every 4 hours and 2 copies are kept all the time. 

However, it will be migrated to Symmetrix 40k and the backup software will be NetWorker and DataDomain.  Since it is SQL, it will be NMM in this case.  Do I need to use AppSync for the VSS quiescing and cloning?  Or will NMM handle both of them?  I work with NMM before but never play with PowerSnap (now, call Snapshot manager?).  It will either be deployed with NW 8.2.x or 9.x.  We have not decided which version yet.
