BackupVirtualDeviceSet::Initialize: CoCreateInstance failure on backup devi

[Andy_ECA]

I am trying to find out why we are having some intermittent problems with our SQL backup.

We are seeing the following in the SQL Server log:-

2005-02-11 02:42:10.43 spid54BackupVirtualDeviceSet::Initialize: CoCreateInstance failure on backup device '

Does anyone have any ideas why we are seeing these entries in the log?

The only entry that's showing on the backup Exec log is that it failed to backup "msdb" because it was in use.

Please HELP!!!!!

Hi,

As per our understanding, this may be caused if Backup Exec is trying to communicate through VDI ( Virtual Device Interface) and SQL is trying to communicate through Named Pipes. Please refer to the following technote:

http://seer.support.veritas.com/docs/248591.htm

This technote also applies to 9.1 of Backup Exec.

Make sure that mssqlserver service is logged in as system account.
We hope this will help.
