Here in this article, you will get a step by step guidance on how to restore an Exchange database to a recovery database. Get a brief on Recovery Database and how it can be used to restore Exchange database in this section!

Commonly known as RDB, Recovery Database is an out-of-the-ordinary mailbox database that permits you to mount and then extract data from a restored mailbox database as part of a recovery process. RDBs allow restoring data from the backup or copy of the database without restricting or disturbing users in accessing the data of the mailboxes saved in the Exchange Server database.

After you create an RDB, you can restore the mailbox database into the RDB by using a backup or by copying a database and its log files into the RDB folder structure. Thereafter, you can use the New-MailboxRestoreRequest cmdlet to extract data from the restored database. Once you extract the mailbox data, you can export it to a folder or merge into an existing mailbox.

Exchange Management Shell for restoring Exchange database to a recovery database

1. Restore the database and its log files or copy the recovered database and its log files, to the place that you will use for your recovery database.


2. With the Eseutil utility, turn the database from dirty shutdown to a clean shutdown state. The syntax for it is as follows:

(Note - In the syntax given above, EXX is the log generation prefix for the database. For instance; E00, E01, E02, etc.)


3. Create a ‘recovery database’ and give it a unique name. However, use the ‘name’ and ‘path’ of the database file for the EdbFilePath parameter. And also, use the location of the restored log files for the LogFolderPath parameter. The syntax for it is as follows:

This example shows the creation of a recovery database that will be used to recover database‘DB1.edb’ and its log files located at ‘E:\Databases\RDB1.’

4. Restart the service named Exchange Information Store. The syntax for it is as follows:

5. Mount the recovery database. The syntax for it is as follows:

6. Confirm that the mounted database comprises the mailbox(es) that you wish to restore:

7. Use the New-MailboxRestoreRequest cmdlet to restore a mailbox or items from the recovery database to a production mailbox. For example:

The example displayed above restores the source mailbox that has the MailboxGUID 1d20855f-fd54-4681-98e6-e249f7326ddd on DB1 mailbox database to the target mailbox with the alias Morris.


8. Use ‘Get-MailboxRestoreRequest’ at regular intervals to check the status of the mailbox restore request. Once the restore has a status of ‘Completed’, use Remove-MailboxRestoreRequest to remove the restore request. The example is as follows:


9. Lastly, confirm if the mailbox and data has been successfully recovered. To do so, open the target mailbox with the use of Outlook or Outlook Web App and check if the restored data is present.


Things to know


You should know the following things before executing the process described above.


  1. You need to have permissions before carrying out this process. You can find the required permissions in ‘Mailbox recovery’ entry of Recipients Permissions topic.
  2. There are some backup applications that can restore Exchange data to a recovery database directly. Windows Server Backup can restore backups to a recovery database that are only ‘file-level’ and therefore it cannot be used to restore backups of ‘application-level’ to a recovery database.
  3. The database and log files that contain the recovered mailbox data must be restored or copied into the Recovery Database folder structure.
  4. The database should be turned into a clean shutdown state from dirty shutdown state. To do so, you can use Eseutil /R utility that is inbuilt in the Exchange Server.


Advantages

  1. Available free-of-cost


Disadvantages

  1. The process is time consuming and tedious.
  2. The steps should be followed correctly and in sequence.
  3. Knowledgeable professionals are required to execute the process correctly.
