Hi all,
Bit stuck here,
On trying to run a Windows Server Backup I am getting errors:
Backup started at '{bf7fe851-53c2-4e67-88f6-05d1d2ce7af4}' failed as Volume Shadow copy operation failed for backup volumes with following error code '2155348129'.
Now I was getting lots of VSS errors and the Hyper-V VSS writer was sitting in a failed state after running backups. I stopped the Hyper-V server and moved old XMLs of machines that don't actually exist (I believe they were manually deleted by whoever installed this server) from C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines to C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines\Old
This fixed my Hyper-V VSS writer issue.
Run Windows server Backup again.. all looks good, I look at Hyper-V manager and I see the message that the snapshot succeeded..
Then same error.
I have looked a bit further into the logs and it looks like Hyper-V is looking for Snapshots of these machines that don't exist:
Cannot find the specified snapshot. (Snapshot ID C74E6D17-60B0-4CA3-B751-41C675DECC25)
Only says this for the machines that don't exist, I have 2 existing machines which are functioning fine.
When I try and run the backup I also get the following error:
Failed to revert to VSS snapshot on one or more virtual hard disks of the virtual machine '%1'. (Virtual machine ID %2)
Is this a permission issue?
The snapshot XMLs exist, I have tried moving them to an \old folder also but it is still looking for them.
If someone could point me in the right direction that would be a massive help.
Cheers
