VSS: An unexpected error occurred when cleaning up snapshot volumes. Confirm that all snapped volumes are correctly re-synchronized with the original volumes.

Hi all,

at a customer’s site I’ve a problem with a fresh installation of Backup Exec 2014. Every backup (full or incremental) always reports the following error: “An unexpected error occurred when cleaning up snapshot volumes. Confirm that all snapped volumes are correctly re-synchronized with the original volumes.”.

On this site I have three servers; the error is only generated for one of them. Here’s a short overview:

Server1: Windows Server 2012 R2, latest patchlevel, physical machine, Domain Controller and Fileserver. Backup Exec is installed on this machine, backup is written directly to SAS tape loader. There error is generated on this server.

Server2: Windows Server 2008 R2, latest patchlevel, virtual machine, running on Citrix Xen Server 6.2. Used for remote desktop services, no errors on this server.

Server3: Windows Server 2012 R2, latest patchlevel, virtual machine, database server with some SQL Instances, no errors on this server.

As I said, error is reported only on server1, no matter if it is a full or an incremental backup. During the backup I found the following errors is the event log (translated from a german system):

Event ID: 12293
Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider. "{89300202-3cec-4981-9171-19f59559e0f2}" an error occured. Routinedetails Error calling Query(). [0x80042302] [hr = 0x80042302, unexpected component error of the Volume Shadow Copy Service.

Process:

   Volume Shadow Copy polling

   Volume Shadow Copy delete

Context:

   Executioncontext: Coordinator

   Executionkontext: Coordinator

And

Event ID: 8193
Volume Shadow Copy Service error: Unexpected error calling Routine "IVssCoordinator::Query" hr = 0x8004230f, Unexpected error Volume Shadow Copy Service Provider

Process:

   Volume Shadow Copy delete

   Executioncontext: Coordinator

There are some articles about this error in the knowledge base or web which does not help or do not apply to my environment for example:

http://www.symantec.com/business/support/index?page=content&id=TECH38338&actp=search&viewlocale=en_US&searchid=1423724381707

What I already have tried:

• Disabled Antivirus during the whole backup
• Installed Service Pack 2 for Backup Exec
• Rebooted the server
• vssadmin list writers do not show any errors
• consult eventid.net for other possible solutions

Anymore ideas from you guys?

Best regards,

Christoph
