Virtual Machine Backup puts CSV into Redirected Access mode

    Question

  • I backup all nine of my production servers that are running in Hyper-V R2. All of my drives are Cluster Shared Volumes. After the backup I can see that all nine backed up onto tape, but when I check my Failover Cluster it shows one CSV in redirected mode. If it's able to backup the VM why is it leaving it in redirected mode? (it's the same one every time I run the backup)

  • If you run VSSADMIN LIST PROVIDERS - what is returned ?   Are there any Application event log messages from VSS or System event messages from VOLSNAP showing errors ?   After the backups complete, when you run vssadmin list shadows, are there any snapshots listed ?

  • Mike,

    Looks like my issue was related to two protection groups trying to run at the same time. My Virtual Machine backup was running into my File Share backup so both protection groups were trying to backup the same server. I pushed out my file share protection group so it runs after the VM backup. It's no longer leaving my CSV in redirected mode.

  • Hi,

    If you have a VSS hardware provider installed, then we can do parallel backups and that should not cause any problems.  If you only have the system vss software provider, then you should implement csv serialization to avoid parallel backups running.

    see the following article:
