Few Cases of Exchange Server Disaster Recovery

In order to understand the disaster recovery easily, we have discussed two examples and described how to recover from them. You can also use the approaches shown in these examples to know what to do in those situations.

Example 1 – Exchange Active Directory Crashed

Before initializing the restoration process of the Exchange Server and bringing it to the active state, first assure that you have at least one copy of Exchange database. Such DB copy is usually in the healthy state which makes it easy for us to restore. To begin the recovery process, follow the below pre-requisites:

  • Create a backup of Active Directory State to recover items like distribution lists, contacts, etc.
  • Save a backup of Exchange database as both offline and online locations.
  • Prepare a note of your domain with Exchange Server organization name and the name of the administrative group.

Now, let’s start recovering the offline copy of Exchange database.

  • Implement the ESEUTIL command to assure that the database is in healthy condition. This has to be performed before recovering the data in MS Exchange.

Eseutil/mh “c:\Restored Offline Backup\priv1.edb”

  • Now, make sure that organization name and administrative group name is same without which you cannot mount Exchange DB. To implement this, implement the following command in CMD:

C:\>find I “OU=””C:\Restored Offline Backup\priv1.edb”

  • Try to mount the database after executing the above command. But, before mounting database, navigate to Mailbox Store Properties and choose the checkbox which displays “This Database can be overwritten by a restore.”
  • Go to Exchange System Manager, Tools and then Mailbox Recovery Center.
  • Right click on it and choose Add Mailbox Store.
  • Right click on all the mailboxes except the system mailbox. Click Export.
  • Click Next on the appeared window and then mention the destination container.
  • Choose “Append the new definitions at the end of the file” option and click Next. It will export the file to LDF format.
  • After the completion of the export process, open LDF file and confirm all objects.
  • Finally, import all objects to a new blank Active Directory by implement following command:

C:\>ldifde -i -f C:\import.ldf

  • Reconnect all the mailboxes using Mailbox Recovery Center. Right click on the mailboxes and press Find Match. It will discover all the user accounts which are exported recently. Click Reconnect to finish the working.

Example 2 – Exchange Server Crashed

A failed Microsoft Exchange Server can be restored using an exclusively created recovery database. It is a mailbox DB which allows you to mount the restored mailbox data and retrieve data from it as part of the recovery process. It allows you to recover data from a backup or copy it without causing any problem to the users accessing current data. The New-MailboxRestoreRequest cmdlet can be used to extract data from DB. After retrieval, the data can be exported to a folder or merged into an existing mailbox.

Automated Solution for Exchange Server Disaster Recovery Plan

The above-mentioned techniques are successful in extracting the crashed database or Active Directory. These methods might seem so technical for the administrator who hasn’t yet faced any disaster. Therefore, executing these steps does not only require extreme concentration but also needs permissions. Another problem is that these procedures fail to recover crashed Server. So, a better technique to overcome these issue is to use an automated solution i.e. Exchange Mailbox Recovery Tool. This software is capable enough to find every bit of recoverable data without any hassle.
