Server backup failing because SPSearch4 VSS Writer

[guest]

I have just installed Small Business Server 2011 and I installed SP1 for 2008 R2 today. I cannot succeed with Windows Server Backup Backup Once operation. This is the first time I am trying to run Server Backup.



I get following error message:



------

The backup operation that started at '‎2011‎-‎07‎-‎12T14:13:04.651000000Z' 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 '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

------



When I check from Application logs, I find following error message timestamped the same as above error message:



------

Volume Shadow Copy Service error: Failed resolving account spsearch with status 1376. Check connection to domain controller and VssAccessControl registry key.

Operation:
PostSnapshot Event

Context:
Execution Context: Writer
Writer Class Id: {be000cbe-11fe-4426-9c58-531aa6355fc4}
Writer Name: ASR Writer
Writer Instance ID: {96058494-f42f-4134-a338-ad329f548a87}

Error-specific details:
Error: NetLocalGroupGetMemebers(spsearch), 0x80070560, The specified local group does not exist.
------



When I check from Active Directory Administrative Center, I can see that account spsearch does exist. All services are up and running.



When I restart server and run "vssadmin list writers" in PowerShell, there is no errors but after failed backup attempt I get error for 'SPSearch4 VSS Writer' below



------

Writer name: 'SPSearch4 VSS Writer'
Writer Id: {35500004-0201-0000-0000-0
Writer Instance Id: {6d7435c2-c142-48
State: [8] Failed
Last error: Inconsistent shadow copy

After installation of server software I havent done nothing that would influence SharePoint but that seems to be the fault why backup is not succeeding. Any help would be appreciated!!



I also can see following related errors in Application log after "Search service started" Informational for SharePoint:



------

Event 70, SharePoint Foundation Search

The mount operation for the gatherer application 672cd3b8-3348-4f10-bc99-3a01d930e5aa has failed because the schema version of the search administration database is less than the minimum backwards compatibility schema version supported for this gatherer application. The database might not have been upgraded.

I found a similar case is our database and please have a try on steps below:

1. Open the command prompt as administrator.
2. Go to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN
3. Execute the following command:

PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures

After completing the above command restart the server and try to perform the backup operation again.
