Configuring Consistency Checks for Exchange Database Backups

Applies to: Exchange 2007 or later, and IntelliSnap

During consistency checks, also called integrity checks, the database and transaction log files are inspected for errors that might prevent the database from mounting, or that might prevent users from receiving, deleting, or opening messages. If any errors are detected, they are fixed before the database is backed up.

By default, consistency checks are turned off for DAG environments, but are turned on for stand-alone environments.

In addition, you can create pause points so that Exchange system resources are made available periodically to other processes (for example, sending and receiving messages) under the following circumstances:

• Prolonged consistency checks of large databases

• High load on the Exchange server

Procedure

1. From the CommCell Browser, expand Client Computers > client > Exchange Database.

2. Right-click the appropriate subclient, and then click Backup.

   The Backup Options for Subclient dialog box appears.

3. Click Advanced.

   The Advanced Backup Options dialog box appears.

4. On the Data tab, select the Perform Consistency Check check box.

   Note

   You are configuring the consistency check only for this scheduled or immediate backup operation.

5. Optional: Create pause points.

   1. Select the Throttle check for 1 second every check box, and then enter the number of I/O operations to complete before the throttle check is performed.

   2. If the consistency checks only apply to transaction log, select the Perform Consistency Checks for Logs only check box.

6. Click OK.
