Booting the NetVault Bare Metal Recovery Client with the Linux®-Based Plug-in Offline Client

With all relevant networking information noted, you can boot the target NetVault Bare Metal Recovery Client.
To boot the target client:
1
Power down the NetVault Bare Metal Recovery Client, and insert the VaultOS CD (if connected through a USB port, the port must use the 2.x protocol or earlier).
On reboot, there is a 5-second delay after the boot prompt appears.
2
Press Enter to start the sequence immediately.
A series of dialog boxes appear as various applications are loaded to system memory. The initial load sequence may take several minutes, during which time the screen may appear blank.
3
When the Network Connections dialog box appears, select the applicable interface, and press Edit.
 
* 
IMPORTANT: You can only use one active network interface during the backup and restore operation.
4
In the Editing Network Interface dialog box, configure the IPv4 and IPv6 settings for the selected network interface.
5
When you are finished, press Apply to return to the Network Connections dialog box, and then press Close.
The Client is now prepared for backup or restore.

Booting the NetVault Bare Metal Recovery Client with the Windows® PE-based Plug-in Offline Client

With all relevant networking information noted, you can boot the target NetVault Bare Metal Recovery Client.
To boot from a standard Plug-in Offline Client CD:
1
Power down the NetVault Bare Metal Recovery Client, and insert the Plug-in Offline Client CD (if connected through a USB port, the port must use the 2.x protocol or earlier).
On reboot, the NetVault Bare Metal Recovery interface appears.
2
When the BMR Network Configuration dialog box appears, select the applicable option:
•
Use DHCP (recommended): To use the Dynamic Host Configuration Protocol (DHCP) to configure the network interface, select this option.
•
Use Static IP Address: To enter specific IP addresses, select this option, and enter the addresses in the IP Address, Subnet Mask, and Default Gateway fields.

You can use the list above the Run button to output information related to the NetVault Bare Metal Recovery GUI when you issue the Run command.
Also, the information displayed in the text window is automatically exported to the “x:\dellbmr\bmr_gui.log” file.

Restoring data

The restore of data backed up with the Plug-in Live Client is handled by the Plug-in Server. Backups performed using the Plug-in Live Client are revealed beneath the Plug-in Server node  (labeled “VaultDR APM”) on the Create Selection Set page of the NetVault Backup WebUI.
The sections that follow illustrate all the procedures required to perform a restore of a Plug-in Live Client backup.
•
Restoring to a physical machine
•
Restoring as a VMDK Image
 
* 
IMPORTANT: Verify that the Disk Geometry of the OS targeted by the restore matches the geometry of the source OS that was backed up. If they do not match (for example, the source used 32 sectors per track, and the target uses 63 sectors), an error occurs when the system attempts to start.
Restoring to a physical machine
The following section details the procedure required to recover a Plug-in Live Client backup to a physical machine with the same hardware specifications as the machine used for the backup.
Prerequisites
The restore procedure for a Plug-in Live Client backup is a delicate operation. Before setting up and running a restore, the following prerequisites must be met.
BitLocker volumes
Volumes that are encrypted using BitLocker on Windows Server® 2008 clients lose encryption after restore. If you are using BitLocker, enable encryption again when you restore the machine.
Shadow copies
Windows® uses VSS persistent snapshots to implement shadow copies in Windows Server® 2008. When restored, Windows does not properly recognize these shadow copies. They can become orphaned and consume disk space.
Microsoft® does not recommend backing up shadow copies. However, the Plug-in Live Client performs backups at the block level so there is no way to prevent the backup of snapshot files. Manually delete the snapshot files and enable shadow copies on the recovered volume again.
For instructions on deleting shadow copies, see: http://technet.microsoft.com/en-us/library/cc776119.aspx
For instructions on enabling shadow copies, see: http://technet.microsoft.com/en-us/library/cc776483.aspx
In addition, Dell recommends limiting the amount of space allocated to shadow copies to 300 megabytes (MB). This step deletes the cache files. Alternatively, disable shadow copies.
For further information on Microsoft-recommended best practices for shadow copies, see: http://technet.microsoft.com/en-us/library/cc753975.aspx
Windows® disk management
Windows Server® 2008 automatically assigns drive letters to new-found partitions following a restore. This behavior can be controlled by using the diskpart.exe command. For more information, see http://technet.microsoft.com/en-us/library/cc773140.aspx.
Ensure that device filenames match
The target device name on the NetVault Bare Metal Recovery Client (for example, “Disk 0 (IDE)”) must be the same as it was at the time of backup.
Boot the NetVault Bare Metal Recovery Client with Plug-in Offline Client
Boot the target NetVault Bare Metal Recovery Client with the Plug-in Offline Client to prepare it for the restore of a DR image. To complete the boot process, perform the steps covered in Booting a NetVault Bare Metal Recovery Client with Plug-in Offline Client.
Gather noted Device Size and Disk Geometry information
Have the information noted in Verifying Disk Geometry and Device Size handy to complete the restore. This information helps ensure that you back up the correct data.
Verify access to the target NetVault Bare Metal Recovery Client
The NetVault Bare Metal Recovery Client machine that is to serve as a target for the restore must be accessible to the Plug-in Server. The section that follows outlines the required steps for this verification.
 
* 
NOTE: Dell recommends that the target machine for the restore has the same hardware configuration as the original machine.
1
With the NetVault Bare Metal Recovery Client booted with Plug-in Offline Client, access the NetVault Backup Server, and start the NetVault Backup WebUI.
2
Access the NetVault Backup Backup window to verify that the applicable client machine has been added as a NetVault Bare Metal Recovery Client.
a
Open the Plug-in Server to reveal existing clients.
b
Locate and right-click the applicable NetVault Bare Metal Recovery Client, and select Edit from the pop-up menu.
c
When the Edit Bare Metal Recovery Client dialog box appears, verify that the data is correct or change it as required.
d
If the NetVault Bare Metal Recovery Client is added correctly, continue to the next section, Restore procedure; otherwise, proceed to the following step.
3
Add the applicable NetVault Bare Metal Recovery Client.
For detailed instructions, see Adding a NetVault Bare Metal Recovery Client to the Plug-in Server.
4
Close the NetVault Backup Backup window of the Plug-in Server, and continue to the Restore procedure section.
