SYMPTOMS

When you perform online backups of large information stores with the Database Scrubbing option enabled during backup, the backup process may time out.

CAUSE

Scrubbing the database during backup requires the metadata to be preread. On large databases, it may take longer than the default value of two minutes to preread the metadata. This causes the backup process to time out prematurely.

To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
