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

Context:

   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_U...

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

Hi,

in my case the problem was the missing vss writer "system writer". when you run "vssadmin list writers" check if it's listed. If not, there are several possible solutions which can be easily found via google. In my case they all does not help and I eneded up, reinstalling the whole machine.

Also it's not a Symantec related problem because the cause it is the missing writer which comes from the Microsoft OS.

 

Best wishes & good luck.

Disable shadow copies on the media server and then enable it again. This time remove any limits on the shadow copies

In addition to the above, do enable AOFO in the backup job and set it to use the Microsoft Software Shadow Copy provider.

Hi,

 

forgot to mention that: already done this. There are no limits set for vss on the volume.

Hi,

 

AOFO was already enabled. I changed the setting from "Automatic" to "Microsoft VSS". Manual started a job, error still persist.
