Understanding the SnapManager Configuration Wizard

Functions the Configuration Wizard performs

The SnapManager Configuration Wizard provides the following capabilities:

If Exchange databases need to be moved, the wizard dismounts the databases in a storage group, moves the Exchange database and transaction log files to the selected LUN, and remounts the databases.
The wizard creates a SnapInfo directory that stores information about the backup sets and the backed-up transaction logs.
The wizard disables circular logging for all storage groups that are moved to a LUN, to enable up-to-the-minute recovery of those storage groups.

When to use the Configuration Wizard

You must use the SnapManager Configuration Wizard to move the Exchange databases and transaction logs so that they are placed in the correct location for proper functionality of the SnapManager Backup and Restore processes.

After the initial configuration, you can return to the Configuration Wizard at any time to review or make changes to your Exchange data store configuration.

Caution
Do not use the Exchange System Manager to move Exchange databases or transaction logs for any Exchange system that has been configured using SnapManager. Doing so prevents SnapManager from functioning correctly.

Note
Remember that moving Exchange databases causes them to be taken offline during the move operation.

Understanding the Exchange and SnapManager component properties

When you use the Configuration Wizard, you are determining the placement of several components of Exchange and SnapManager. You can see the current placement of these components by selecting them in the Backup tab window and selecting View > Properties, or by using the Details buttons in the Configuration Wizard.

The following table describes these components and how they are used in your SnapManager environment.

Component	Description
SnapInfo Directory	Contains SnapManager backup information, copies of transaction log files, and other data critical to the backup set. For more information about the SnapInfo directory, see SnapManager Backup and the SnapInfo directory.
SMTP System Path	The directories used by the SMTP queue.
MTA System Path	The directories used by the MTA queue.
Transaction Log Files	The location of the Exchange transaction logs. The SnapManager Configuration Wizard places the transaction log files in this location. The transaction logs contain changes made to the Exchange databases since the last backup, enabling an up-to-the-minute restore.
System Path	Path to the directory that contains the Exchange storage group system files. They are moved to this location by the SnapManager Configuration Wizard. Note For host systems running Windows 2000 Server, the system files must be on a LUN containing that storage group's transaction logs. For host systems running Windows Server 2003, the system files must be on a LUN containing Exchange databases.
Storage Group Database Settings (Database Settings for Exchange 5.5)	Lists the databases for this storage group or Store. To see more information about any of the databases listed, you can highlight the database name and click Details.
Database	Displays the paths for the .edb and .stm files for the selected Exchange database. The .edb file stores message and attachment content generated by MAPI clients, and message properties such as author, recipients, subject, and priority. The .stm file holds native Internet content (for example, MIME).
