I have Symantec Backup Exec 2010R3 and the HyperV agent which I have been using for over a year to back up my HyperV VM's every night. It has worked flawless for this time, until a week ago. Now, what is happening is when it hits just one particular VM, the VM will go into a saved state while the backup starts. It will then reconnect and start back up, but I do lose connectivity to it for about 2-3 minutes while it does that. This has never happened before. I am running 2008R2 SP1 Enterprise with the VM's in a failover cluster with cluster shared volumes iscsi to my SAN. I have tried moving the CSV to other hosts but that has not made any difference. The VM still backs up entirely as I would expect, but Im at a loss for what would all of a sudden make it start going into a saved state. There are several other VM's on the same host server which do not have the same symptoms.
