SYMPTOMS
When you use the Volume Shadow Copy Service (VSS) to take a snapshot shadow copy of a Microsoft Exchange Server 2003 storage group or of an Exchange 2003 store, you experience the following symptoms:  The backup operation fails. In this scenario, the following events are logged in the Application log:   Event Type: Error

Event Source: MSExchangeIS

Event Category: Exchange VSS Writer

Event ID: 9611

Date:

Time:

User: N/A

Computer:

Description: Error code 0xfffff69d when freezing the Storage groups.   Event Type: Error

Event Source: ESE

Event Category: ShadowCopy

Event ID: 2002

Date:

Time:

User: N/A

Computer:

Description: Information Store (5992) Shadow copy instance number encountered error -2403 on freeze. 

Note In these events, &quot;0xffff69d &quot; and &quot;-2403&quot; refer to a Jet_errOSSnapShotNotAllowed event. This event means that VSS cannot do the following while backup is in progress or while recovery is in progress:  VSS cannot take a snapshot shadow copy of a Microsoft Exchange Server 2003 storage group. VSS cannot take a snapshot shadow copy of an Exchange 2003 store.  You use the Windows Backup program (NTBackup) as a test backup program to perform an online backup of the Exchange 2003 storage group. However, the backup operation fails. Additionally, the following error information is logged in the backup report:

Backup started on  at.

The 'Microsoft Information Store' returned 'Backup is already active. ' from a call

to 'HrESEBackupSetup' additional data '-'The 'Microsoft Information Store'

returned 'Functions called in an invalid sequence. '

from a call to 'HrESEBackupClose' additional data '-'

</li></ul>

Note By default, the backup report is named Backup .log. This file is located in the following folder:

%Userprofile%\Application Data\Microsoft\Windows NT\NTBackup\Data

<div class="cause_section">

CAUSE
This problem occurs if the Exchange transaction log files are manually moved or are manually deleted from the transaction log folder when a storage group is running. The VSS process tries to delete each unnecessary log file after a full online backup. If the VSS process cannot find one of the log files, the backup fails and the &quot;backup in progress&quot; flag is not reset.

<div class="resolution_section">

RESOLUTION
To resolve this problem, follow these steps: <ol> On the affected Exchange server, stop the Microsoft Exchange Information Store service. Alternatively, dismount all the stores that are in the affected storage group.</li> Run the eseutil/mh command against each database in the affected storage group. Do this to make sure that each database is in a Clean Shutdown state. For more information about how to do this, visit the following Microsoft Web site:

http://technet.microsoft.com/en-us/library/d8fd559e-6262-4e89-a7fc-457286d0ddf3.aspx

Note Do not continue this procedure until each database is in a Clean Shutdown state.</li> Move all the transaction log files and all the system files from the transaction log folder to a backup location.</li> Restart the Exchange server.

Note This problem may cause the backup process to become locked. When you restart the computer, all active backup processes are exited.</li> Perform a full online backup.</li></ol>
