Volume Shadow Copy Service error event ID 12292

Since we had change the SAN switch for one of our Exchange 2010 DAG nodes, Its started to fetch the event ID 12292 and VSS backup stoped working for this node.

Used below cmdlet to make sure exchange replication  writer and providers are working fine.

Vssadmin list writers

Vssadmin list providers

Started looking the registry value of VSS provider and matching the registry value with other DAG nodes which is working normally. During match, I found the “Start” Dword value is showing data value “0x00000004”.

In other DAG nodes this value was ““0x00000002” under “KLM\CCS\SYSTEM\SERVICES\SWPRV” .

If you falling under same kind of issue, I would suggest you to verify the registry value with working server for below Key’s.

1. On Exchange server, please run regedit, go to verify the following two registry keys. Make sure they are the same with another working server:



2. Please Reboot Exchange server in Off-Business hours.

3. After reboot, please try to backup Exchange using Windows Server Backup tool.  Check if it is successful.

If still you are not bale to managed this working, As a Last resort you can try Re registering the Vss dlls

Re-registering Vss Dlls

cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 /s ole32.dll
regsvr32 /s oleaut32.dll
regsvr32 /s vss_ps.dll
vssvc /register
regsvr32 /s /i swprv.dll
regsvr32 /s /i eventcls.dll
regsvr32 /s es.dll
regsvr32 /s stdprov.dll
regsvr32 /s vssui.dll
regsvr32 /s msxml.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
vssvc /register
net start swprv
net start vss

It does help in getting the Vss service to function properly
