Virtual Backups


#1

I'm not too familiar with Virtual backups. I see this in the log:
TYPE=VIRTUAL_DEVICE: {'{C81A3B9D-99F6-422D-AF7E-F7EE43209883}3'}).

It's happening everyday. We're trying to find out where this cam from.

I don't understand why SQL Server doesn't provide a filename?

Is there anyway to find out where this originates from?

You probably need to search for VSS.

The most likely causes are Tape Backups, SAN Backups/Snapshots or VM Backups/Snapshots done by your systems people.

This and similar are worth a read:
