Event ID 206 is logged when you try to run an incremental Volume Shadow Copy Service (VSS) snapshot backup on an Exchange 2003 server

Consider the following scenario. You run a full Volume Shadow Copy Service (VSS) snapshot backup or a previous VSS snapshot incremental backup on a server that is running Microsoft Exchange Server 2003. Additionally, a soft recovery is performed successfully on the Exchange store after the Exchange store experiences a dirty shutdown. When you try to run an incremental VSS snapshot backup, the operation fails. Additionally, the following event is logged in the Application log:

Event ID: 206
Source: ESE
Category: Logging/Recovery
Type: Error
Description: Information Store (1156) First Storage Group: Database <path to database> cannot be incrementally backed up. You must perform a full backup before performing an incremental backup.

During the soft recovery, the Exchange store changes the backup type in the database header from snapshot to normal.
