Hello,

I would like to backup my PI server (installed on windows server 2008) with a 3rd party (Netbackup), but while backup's running i have this error on the event log

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface.  hr = 0x80040154, Class not registered

. This is often caused by incorrect security settings in either the writer or requestor process.

Operation:

   Gathering Writer Data

Context:

   Writer Class Id: {0fd0891d-b731-4e59-a35d-48f164383155}

  Writer Name: OSISoft PI Server

   Writer Instance ID: {0213457f-e892-4cde-a1a2-efb02c3ec707}

 

Should I add this VSS Writer ?

Please how can I resolve this problem, Thank you for your help
