  1. Ensure that the source and destination computer satisfy the prerequisites.
  2. Create an Offline Copy.
  3. Mine and Restore the required attributes and objects from the Offline Database to the live active directory (source) database.

Prerequisites

Before creating the offline copy, ensure that the source and destination clients satisfy the following requirements:

Source Computer

Destination Computer

Ensure that the computer has one of the following Windows operating systems:

  • Microsoft Windows Server 2003
  • Microsoft Windows Server 2008
  • Ensure that the Microsoft Windows operating system and Active Directory iDataAgent are installed on the destination computer.

Creating an Offline Copy of the Database

You can take a snapshot of the live active directory database and restore it to the destination computer to create the offline database

Creating a Snapshot

Follow the steps given below to create database snapshots:

Restoring the Snapshot

Once you have the database snapshot, you can select from either one of the methods to create offline copy of the database:

Method 1: Mount and copy files

Method 2: Perform an Out-of-Place Restore

Method 1: Mount and Copy Files

  5. In the Mount Path dialog box, specify the destination client and the path on the client in the Destination Client and Destination Path fields.

    On a Windows platform, enter a CIFS Share Name for the Agent.

  6. If you do not wish to save any changes made to the mounted snapshot after the snapshot is unmounted, select Protect Snapshot during mount.
  7. Click OK.
  8. Click Close on the Snaps created during SnapProtect operation dialog box.

If you do not select Protect Snapshot during mount,the changes made to snapshot when it is mounted will be retained after the snapshot is unmounted and the snapshot can no longer be used for restore.
