Refer to the following instructions to restore Microsoft Exchange Server 2003 / 2007:




• Prepare the operating system for the Exchange Server restore (if required).



Install the original version of Windows and Exchange Server (with the same level of service pack installed as in the original system).>/p>



• Restore Windows Active Directory (if required).



Restore the System State data from AhsayOBS, and then restore the System State using Ntbackup / WBAdmin.exe.

Refer to the "How to restore Windows System State" chapter for detailed instruction.




• Install AhsayOBM (if required).



Refer to the Installing AhsayOBM chapter for details instruction.




• Startup the [Microsoft Information Store] services from Windows Services.
• Restore the Exchange database from backup; restore the database backup files from the AhsayOBS server.



Please ensure the directory structure is the same as it appears in the File Explorer:






Directory Structure

-->[Restore Destination] ------>[Server] ---------->[Microsoft Information Store] -------------->[First Storage Group] ------------------>[Database] ---------------------->Priv1.edb ---------------------->Priv1.stm ------------------>E0000001.log -------------->[Second Storage Group] ------------------>[Public Folder Store(Server)] ---------------------->Pub1.edb ---------------------->Pub1.stm ------------------>E0100001.log





If a different version of the database to be restored exists on the MS Exchange server, please dismount it from the services using System Manager or Exchange Management Console for MS Exchange 2003 and 2007 respectively.




• Use the [ExchangeRestore32.exe / ExchangeRestore64.exe] file found from the AhsayOBM [bin] directory to restore the database.



For 32bit MS Exchange installation:
${OBM-Install-Home}\bin\ExchangeRestore32.exe

For 64bit MS Exchange installation:
${OBM-Install-Home}\bin\ExchangeRestore64.exe


Example

For restore of all databases from backup data [E:\Backup] to an Exchange Server named [win2k8] using the temporary directory [E:\Temp]

Backup data source = E:\Backup
Temp folder for restore process = E:\Temp
Exchange server name = Win2k8

The following command can be used:

[End] Restoring transaction log - 'First Storage Group' [Start] Applying transaction log ... [End] Applying transaction log





Mount the Exchange database afterward in System Manager (for Exchange 2003) or Exchange Management Console (for Exchange 2007).




• Repeat the same procedure for each database to be restored.



Note:
Verify under the Event Viewer if there is any error generated during the restore process.




• If the restore process failed with errors such as bad signature, or null error, the backed up database file restored may be incorrect.



Please try to manually restore and mount the database and log files.


Mounting database file manually



• Dismount the Exchange database using the System Manager for Exchange 2003, or Exchange Management Console for Exchange 2007.
• Copy all restored database and log files to the Exchange database folders.
