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:

      \Parameters\Database log files path

   database path.

   path.
