SYMPTOMS
When you attempt to dismount a database, you may receive the following error message:

The operation cannot be completed because a backup process of the targeted store(s) is currently running.

ID no: c1041733

Exchange System Manager

In addition, the following event ID message may be logged in the Application event log:

Event Type: Error

Event Source: MSExchangeIS

Event Category: General

Event ID: 9521

Date: 3/14/2001

Time: 9:44:00 AM

User: N/A

Computer:

Description: The database &quot;First Storage Group\Mailbox Store &quot; cannot be unmounted because Backup is in progress.



CAUSE
This behavior can occur if a backup process is running against another store (public or mailbox) in this same storage group. In this case, you cannot dismount another database in this storage group.



WORKAROUND
To work around this behavior, wait for the backup of the other database to complete, and then attempt to mount the database.



STATUS
This behavior is by design.



MORE INFORMATION
For more information, click the following article number to view the article in the Microsoft Knowledge Base:

288643 Cannot mount database if you are backing up another database in the same storage group

In some scenarios, the backup application exits with an error and does not reset the bit on the storage group. When this occurs, the error that is generated is similar to the error that is generated when the backup application is still running. Therefore, waiting for the backup to finish is not an option because the backup is already stopped.

To work around this scenario, restart the Microsoft Exchange Information Store service to reset the bit. As a safety measure, we recommend that you move mailboxes to another storage group, dismount the mail stores, and then restart the Microsoft Exchange Information Store service.
