Hello
I am currently having issue with backing up Hyper-V servers on a 2008 R2 machine. Backups were working until 2 weeks ago
I have also been look at the vss writers and it seems it's been stuck in waiting for completion. i have rebooted and uninstall and reinstall WSB and still the writer is stuck at waiting for completion.
Writer name: 'Microsoft Hyper-V VSS Writer'
Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
Writer Instance Id: {d4b387f3-2805-41ee-993d-72eacbc613bc}
State: [5] Waiting for completion
Last error: No error
The WSB in the event log was
The backup operation that started at '2011-06-16T15:59:42.847000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348001'.
Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
I have look up the error code and it seems to be a time out issue of WSB
I am currently suspecting it is the multiple shadows copy's that are stuck. As when i type vssadmin list shadows there are multiple shadows that seem to have been generated when I tried to create the backups via WSB.
I tried deleting the shadow but it would not allow me and instead stated i have to delete them with the backup application in which i created them with.
Does anyone know how to delete the shadows from WSB? Or is there a fix for this issue??
Thanks!
