I have System Center Data protection Manager 2012 installed in Windows Server 2008 R2, with SQL Server 2012. We are successfully taking Bare Metal Backup of more than 100 servers via SCDPM.
But 4 nos. of web servers backup is failing since beginning. When I run consistency check or resume backup, it fails instantaneously with error of VSS.



I have checked all the VSS shadows, writers and providers all is fine. I have applied every solution provided for the likewise problems in internet, nothing worked.
Attached the snapshot of the error and VSSAdmin outputs.
I am getting an error in VSSADMIN list shadowstorage: A volume shadow copy service component encountered an unexpected error.

Can anyone help?
