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.
