The Extract Wizard allows you to restore previously backed up files to a specified folder (an alternate location).
Restoring backed up files to an alternate location allows you to use the files as a standalone data source, or to replace existing files on a given computer. The wizard lets you select a backup, choose the components to be extracted from that backup, and specify the destination folder. Then, the wizard guides you through the extract operation.
The Extract Wizard can help you to perform an authoritative restore of the SYSVOL. For more information, see Restoring SYSVOL authoritatively.
Also you can use the Extract Wizard in conjunction with the Install from Media (IFM) feature of Windows to create a domain controller. IFM allows you to create an additional domain controller using a restored backup of another domain controller. The restored backup can be held on any backup media (tape, CD, or DVD) or on a shared network resource. A restored backup makes it possible to set up an additional domain controller in an existing domain without replicating the entire directory database to the new domain controller.
With the Extract Wizard, you can restore a backup of a domain controller’s Active Directory to a specified folder. Then, using the restored backup files, you can create a new domain controller, as described in the following sections:
This section describes how to create a Windows Server 2008 R2-based domain controller from a backup by using the Install from Media (IFM) feature of Windows and the Extract Wizard.
To create a domain controller, complete these steps:

Make sure you install the Active Directory Domain Services server role on the Windows Server 2008 R2-based computer you want to designate as the new domain controller.
On that computer, click Start, click Run, type dcpromo /adv, and press ENTER.
On the initial page of the Active Directory Domain Services Installation Wizard, make sure you select the Use advanced mode installation check box.
Step through the wizard until you are on the Choose a Deployment Configuration page.
Click Existing forest, and then click Add a domain controller to an existing domain.
On the Network Credentials page, specify the account credentials you want to use.
Step through the wizard until you are on the Install from Media page.
Click Replicate data from media at the following location, and then specify the location to which you extracted the backup in Step 1: Create and extract a backup.
