SYMPTOMS

Consider the following scenario. You have a computer that is running Windows Server 2008 R2 or Windows 7. You use the IVssBackupComponents::AddComponent method to add several thousands of components into a backup components document. In this scenario, the call to the DoSnapshotSet method takes a long time to be completed. Specifically, you notice a long delay between the PrepareBackup event and the PrepareSnapshot event.

CAUSE

This issue occurs because the IVssBackupComponents::AddComponent method takes a long time to scale each component. This causes a long delay when several thousands of components are backed up.
