I have windows server 2008 r2 installed, Only service running on it is hyper-v.

I am trying to take backup using windows server backup feature and it fails with following error in eventlog

The backup operation that started at '?2009?-?08?-?22T18:42:14.123000000Z' 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 '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

Above error itself is point to other event logs for more detail but i can't find anything in event logs

Then i ran following command

vssadmin list writers

It had following out of ordinary in list

Writer name: 'Microsoft Hyper-V VSS Writer' Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} Writer Instance Id: {d15c5f78-121c-464f-b23b-f285e919b05c} State: [8] Failed Last error: Inconsistent shadow copy

How could i resolve this?
