Windows 2008 R2 backup fails with event 521 error code 2155348001

Windows Server 2008 R2 SP1.  Hyper-V role installed.  OS on drive C.  All VMs stored on Drive D.

I am attempting to run a Bare Metal backup of the host system to a network share.  Drive D is not included in the backup job.  I am getting the following error:

Log Name:      Application
Source:        Microsoft-Windows-Backup
Date:          1/10/2014 11:28:52 PM
Event ID:      521
Task Category: None
Level:         Error
Keywords:     
User:          SYSTEM
Computer:      SHAQTUS.scdl.local
Description:
The backup operation that started at '2014-01-11T04:08:50.683000000Z' 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.

Reviewing event details, as suggested, does not offer any solution.

I have tried the suggested solutions in other similar threads of increasing the timeout value with the registry entry.  This does not work.

I have not tried reregistering the VSS writers manually, as the only links I have found are for server 2003/2008 (not R2) and explicitly state that they wont work on higher versions of the OS, since they now utilize manifests and the manual procedure could cause problems for those servers. Haven't found similar procedures for 2008 R2.

I have been able to narrow this down a bit.

A Windows 2008 R2 SP1 server with Hyper-V installed backup to a network share is successful;

Install the DPM 2012 agent same backup fails with the 2155348001 error.

We use DPM 2012 to backup VMs, but DPM cannot perform a bare metal backup/restore of server and the 2012 version no longer has the DPMSRT feature.  I prefer to run Bare Metal Backup to a file server share.

Stuck on this one.

Hi, 

The issue is related to DPM, I would suggest you ask for help from DPM forums:
