Exchange Mailbox Restore with Kroll Ontrack (Kroll Restore)

Follow

Topic

This article describes the procedure to restore Exchange mailboxes by using Kroll Ontrack PowerControls for Exchange.

Environment

  • Datto SIRIS
  • Datto ALTO
  • Kroll Ontrack PowerControls for Exchange Version 9.2

Index

Description

If you are restoring from an ALTO 3, proceed to Section 2: Licensing Information. If you are restoring from any other ALTO appliance that is not on per-agent pricing, see Exchange Mailbox Restore With Kroll Ontrack For ALTO (Kroll Restore) to get started.

Licensing Information

The Kroll Ontrack PowerControls for Exchange licenses bundled in the Datto SIRIS are for Exchange Databases for 500 users or less.

Kroll licenses expire after a set period. If the license on your device shows expired, you'll need to provision one from the same location. Datto provides this license on SIRIS devices at no additional charge].

ALTO users not on per-agent pricing must purchase this service at an additional cost. Contact your Sales Executive, or navigate to the Purchasing & Billing → Service Billing category on the Datto Partner Portal, if you need to purchase a Kroll license for an ALTO appliance.

If your Exchange Database contains more than 500 users, contact Datto Technical Support to start a recovery. If time is a critical factor, ask your Support Technician how long the recovery may take; large databases can take several hours or more to process, depending on their size. Be sure to note the number of mailboxes you need, as shown in the figure below.

  • 1024 MB RAM minimum
  • 200 MB of free hard disk space for the installation of Ontrack PowerControls
  • Monitor with 800 x 600 or higher screen resolution

Performing the Restore

Offsite Restore Preparation

  • To do a Kroll restore from an offsite recovery point, follow the steps in Mounting a Secure FTP File Restore in the Recovery Launchpad to create the cloud share. You can then use Netdrive to mount the SFTP share to a local environment with the required software installed.
  • Alternatively, download the needed EDB file to your local environment, and instead of performing Step 7, use the path to the EDB file's download location. If the file is too large to download, consider a Reverse Roundtrip.

When you have completed these steps, proceed to the Configuring Microsoft Office Outlook step of this article.

Do not leave offsite file restores mounted longer than necessary. Leaving restores mounted when they are not in use can affect your offsite retention usage, and may result in overage charges. 

Configuring Microsoft Office Outlook

1. Make sure that you installed Office Outlook, and that it has run once.

2. Set up an email account on an Exchange Server.

3. For versions of Outlook that distinguish between Corporate Email, use Corporate Email when configuring Outlook.

4 Re-run Outlook, and connect to the Exchange Server.

Obtaining the Kroll License

Click the Advanced tab, then select the Granular Restore tab of the Datto web interface.

This option will not appear in the Device UI on ALTO 2 continuity devices. Contact Datto Technical Support for assistance with performing a mailbox restore on an ALTO 2.

Kroll Licensing for Previously-Installed Instances

If you are following this procedure for a previously installed version, be sure to download the file into the folder in which Kroll was already installed. The default path for Kroll installations is: C:\Program Files (x86)\Kroll Ontrack\Ontrack PowerControls\. Then, proceed to Performing Exchange Message Level or Mailbox Level Restoration. 

Installing Ontrack PowerControls

1. Install and configure Outlook as described in Configuring Microsoft Office Outlook, above.
2. Turn off any disk utility or antivirus program running in the background.
3. Download and run the installer from the Datto appliance's Advanced  Granular Restore tab.
4. Select Install Ontrack Power Controls to start the installation process.

Performing Exchange Message Level or Mailbox Level Restoration

Mount a Recovery Point in the Datto Appliance GUI

1. On your Datto appliance, perform a Local File Restore of the recovery point from which you would like to restore. Make a note of the Samba Share path of the restore.

Configuring the Kroll Ontrack Data Wizard

1. Launch Ontrack PowerControls for Exchange. You will see the Data Wizard shown in Figure 9. If the Data Wizard does not appear automatically, you can launch it by clicking File  → Use Wizard in the Ontrack PowerControls for Exchange UI.

2. Click Browse, then navigate to the Samba share path in the file name section.

3. Navigate through the directory tree of your file restore and locate the EDB file you would like to restore. Select the EDB file, and click Open.

4. In the Data Wizard, the EDB PathLog File Path, and Temporary File Path fields will auto-populate. Click Next to continue.

5. Select the Target Type to which you would like to restore the contents of the EDB (Figure 12.1), and then use the Browse button to select the Target (Figure 12.2). When you finish making your selections, click Next to continue.

6. The Data Wizard will display the message "Now Processing Data File," as it processes the EDB file. The processing takes place in three stages:

  1. Pre-scanning the log files (integrity check)
  2. Scanning the log files (playing the log files)
  3. Hashing the EDB file (building a folder hierarchy)
If Ontrack PowerControls encounters corrupt or missing log files during log playing, you will have the option to continue without playing the logs. If you choose to continue, Ontrack PowerControls will process the EDB without logs.

7. The Data Wizard will close. You will see the results of your recovery displayed in the Source and Target panes in the main Ontrack PowerControls window.

8. For advanced information about working with or managing your recovery, or for information about recovering from non-EDB sources, see the Ontrack PowerControls User Guide (external PDF).

To prevent conflicts with retention operations on your Datto appliance, remove the Local File Restore you used for the Exchange mailbox restore when you are done performing the mailbox recovery.
