XADM: How To Restore an Offline Backup of the Directory Service and Information Store

MORE INFORMATION

An Offline backup of the directory service and information store is made by stopping the Exchange Services and copying the contents of the Exchsrvr\Dsadata and Exchsrvr\Mdbdata directories respectively, from each drive on the computer running Microsoft Exchange Server.

If you have an offline backup of the Microsoft Exchange directory service and information store, follow the steps below to restore this backup:

1. Stop all the Microsoft Exchange services.
2. Determine the location of the database and logs for the directory service and information store service, from the following registry locations:

   Directory Service log path

         HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeDS
         \Parameters\Database log files path
       
   						

   Directory Service database path

         HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeDS
         \Parameters\DSA Database file
       
   						

   Information Store Service log path

         HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS

5. Copy the Priv.edb file to the private information store database path.
6. Copy the Pub.edb file to the public information store database path.
