Hi,
We are using Veeam Backup and Replication 8 to backup SBS2008 SP2 virtual machine. Veeam is installed on a workgroup Hyper-V host server running Windows Server 2012. The SBS server is running SQL express, Exchange 2007 and SharePoint foundation. We started having issue recently with the VSS backup for the SBS server:
Hyper-V VSS writer retryable error when trying to backup with VSS enabled.
This Hyper-V VSS writer error gets resolved after restarting VMM service on the host.
Also seeing Exchange related errors:
- Exchange VSS writer has unsuccessfully completed the backup of storage group. No log files have been truncated for this storage group. Event 9782
- Information Store Shadow copyu instanace aborted. Event 2007
We have tried:
- run Windows Server Backup with VSS full backup - Backup job completed successfully
- run Veeam backup with VSS disabled - Backup job completed successfully
However when we run vssadmin list writers on SBS server, it shows no error for the Exchange VSS writer.
We have already contacted Veeam and they have run some diagnostics and confirmed it is related to Windows Server.
Could it be SQL or SharePoint VSS writiers interfering with Exchange VSS writer?
Please provide some assistance on how to resolve this issue.
Thanks
