Also, System Writers and few other writers will fail after running Backup Exec backup job.
This issue occurs after installing service pack 1 for SharePoint 2010. Windows event log refers to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\VssAccessControl registry key. After installing SharePoint 2010 SP1, two new user accounts are created.
1.<Domain>\spsearch = dword:00000001
2.<Domain>\spfarm = dword:00000001
Ideally, there should be just one account "NT Authority\NetworkService".
Note: Please do not delete these accounts as Microsoft has added them for some reason.
1. SharePoint 2010 databases need to be upgraded after installing service pack 1. Please follow these steps:
i. Open an Administrative command prompt.
ii. Change directory to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN
iii. Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures
It will take some time to upgrade databases. Please refer to Microsoft blog for more information:
2. Reboot the server and re-try backup job.
3. In case backup job and VSS writers still fail, follow these steps:
i.Add the backup account in the following registry
Note: Right click on VSSAccessControl->Permissions. Add backup account there and give it FULL control. Also, make sure Administrators group is owwner of this key.
ii. Open a command prompt and type the command "Vssadmin list Shadows"
iii.If a snapshot exists, it will be listed. Before attempting to delete the snapshot make a note of the time at which it was taken. This will help to determine if the orphaned snapshot was created during or outside a backup. If the snapshot was created outside a backup, check for scripts or application that could have created it (for example some applications take snapshots by creating Scheduled Windows tasks).
iV- Make a note of the ShadowId and use command "Vssadmin delete shadows /Shadow=<ShadowId>" to delete it.
V. Reboot the server and re-try backup job.
4. Please contact Microsoft in case backup still fails.
