Restore procedure

The procedure for restoring a DR restore to a physical machine includes the steps outlined in the following sections:
•
Selecting data for a restore
•
Setting restore options
•
Finalizing and submitting the job
Selecting data for a restore
To select data to restore:
1
In the Navigation pane of the NetVault Backup WebUI on the NetVault Backup Server, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select Plug-in Server from the Plugin Type list.
3
To filter the items displayed in the saveset table further, use the Client, Date, and Job ID lists.
The table displays the saveset name (Job Title and Saveset ID), creation date and time, and size. By default, the list is sorted alphabetically by saveset name.
4
In the saveset table, locate the applicable client, and select the applicable item.
When you select a saveset, the following details are displayed in the Saveset Information area: Job ID, Job Title, server name, client name, plug-in name, saveset date and time, retirement setting, Incremental Backup or not, Archive or not, and saveset size.
5
Click Next.
6
On the Create Selection Set page, select the data that you want to restore.
•
To restore the entire disk, click the box to the left of the applicable disk title to select it.
•
To select specific items, double-click a disk to open it, and then select the items that you want to restore.
•
The Dos Compatibility Region is the first 32k to 512 bytes from start of the disk that immediately follows the Master Boot Record (MBR). NetVault Bare Metal Recovery backs up this region to support GRUB Stage 1.5. However, this region is always backed up and restored regardless of the existence of GRUB Stage 1.5. This option is not selectable.
•
Master Boot Record & System Partition
•
Individual Partitions
Setting restore options
1
On the Create Selection Set page, click Edit Plugin Options, and select Physical Machine (the default) as the Restore Type to restore the backup of a client to a physical machine.
When Physical Machine is selected, the Physical Recovery Options frame containing the Restore Name field is shown. The default value of this field is the NetVault Backup name for the NetVault Bare Metal Recovery Client from which this backup was originally performed (based on the backup saveset selected). This name is associated with a specific IP address that was previously configured. If this value is left at its default setting, selected data is restored to the machine that was originally backed up. You can use this field to relocate restored data to a standby NetVault Bare Metal Recovery Client, if necessary. (For complete details on this procedure and its use of this option, see Recovery to a standby NetVault Bare Metal Recovery Client.)
If you are using the Windows® PE-based Plug-in Offline Client, selecting Physical Machine also makes the driver-related fields available. These options support using different hardware during a restore.
2
If you are using the Windows® PE-based Plug-in Offline Client, complete the applicable options:
•
Inject Boot-Critical Device Driver: If you are restoring to different hardware that also uses a different mass storage controller, select this option. After you select this option, the Boot-Critical Driver Directory and Driver Injection Only options become available.
•
Boot-Critical Driver Directory: If you selected the Inject Boot-Critical Device Driver option, enter the complete path to the local drive where the drivers for the mass storage controller are stored.
•
Driver Injection Only: If you previously completed a restore but pointed to an incorrect location in the Boot-Critical Driver Directory field, select this option to run the driver-injection portion of the restore process again. This option eliminates the need to restore the data again, but lets you inject the correct drivers. Check that you enter the correct path in the Boot-Critical Driver Directory field. (By default, the Inject Boot-Critical Device Driver option remains selected; do not clear it as this options prevents the Driver Injection Only option from working.)
Finalizing and submitting the job
The final steps include setting additional options on the Schedule, Source Options, and Advanced Options pages, submitting the job, and monitoring the progress through the Job Status and View Logs pages. These pages and options are common to all NetVault Backup Plug-ins. For more information, see the Dell NetVault Backup Administrator’s Guide.
To finalize and submit a restore job:
1
Click Ok to save the settings, and then click Next.
2
In Job Name, specify a name for the job if you do not want to use the default setting.
Assign a descriptive name that lets you easily identify the job when monitoring its progress. The name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. On Linux®, the names can have a maximum of 200 characters. On Windows®, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
3
In the Target Client list, select the machine on which you want to restore the data.
 
* 
TIP: You can also click Choose, and then locate and select the applicable client in the Choose the Target Client dialog box.
4
Use the Schedule, Source Options, and Advanced Options lists to configure any additional required options.
5
Click Save or Save & Submit, whichever is applicable.
You can monitor progress on the Job Status page and view the logs on the View Logs page. For more information, see the Dell NetVault Backup Administrator’s Guide.
Notes
•
If selecting individual partitions for a restore, also select the Master Boot Record and System Partition item. Failure to do so results in a failed restore.
•
When performing a restore of a Plug-in Server backup, options available in the Target Client list should be left at their default settings. If a target other than the intended is selected from this list the restore fails.
•
If you select the inject driver-related options, NetVault Bare Metal Recovery attempts to inject the drivers into every disk during the restore process.
•
After completing a restore to a different machine, a “disk read error” occurs when you start the new machine if the size of the Integrated Drive Electronics (IDE) disk does not match the size of the IDE disk on the original (backed-up) machine. To work around this issue, change the disk size in the BIOS to match the original machine.
•
If you are using the Linux®-based Plug-in Offline Client with IDE/Parallel Advance Technology Attachment (PATA) disks and the backup was created using Plug-in Offline Client v5.6.4 or earlier, use the Rename feature to force the system to reexamine and map the disk correctly. Partitions backed up before v5.7.1 are named using an “hd<x>” format, while v5.7.1 and later use an “sd<x>” format. Failure to use the rename feature causes the restore to fail with a “Error: All disk name requested from client is not equal to the backup disk name /dev/hda” message.
•
If you are using the Linux-based Plug-in Offline Client and you are migrating a physical server to a virtual environment in which the Client is Windows®-based, install the disk drivers on the OS before you back up the machine. For more information, see NetVault Bare Metal Recovery physical-to-virtual recovery.

Post-restore

After restoring a backup to a different machine, the following points must be reviewed, and applicable actions must be taken:
•
Bring SAN disks online (Windows Server® 2008 only): If you are using the Enterprise or Datacenter Edition of Windows Server 2008, the default policy for storage-area network (SAN) disks does not include automatically mounting them (this issue does not apply to drive C). After the restore is completed, use Disk Management to set the disk to online.
•
Network connection renamed: Because a different network card is in use, the Network Connection is automatically renamed to local area connection 2.
•
Physical address: Because a different network card is in use, the physical address (Media Access Controller [MAC]) is different. If you use applications that rely on this address, work with the application’s vendor to address the change.

Restoring as a VMDK Image

This option lets you recover backups of the client to a VMDK Image, which can then be attached to a virtual machine created from VMware®. This option converts the backup of a physical machine to a virtual machine.
Plug-in Server must be installed on the NetVault Backup Server.
This procedure includes the steps outlined in the following sections:
•
Selecting data for a restore
•
Setting restore options
•
Finalizing and submitting the job
•
Creating the virtual machine

* 
IMPORTANT: If restoring to a VMDK Image, both Master Boot Record & System Partition and the individual partitions or the restore job fails.

Setting restore options

1
On the Create Selection Set page, click Edit Plugin Options, and select VMDK Images as the Restore Type.
This type of restore provides two additional options — either to restore the VMDK Image to a local directory of the NetVault Backup Server or to restore to a remote ESX® Server.
2
If you want to restore the VMDK Image to a local directory of the NetVault Backup Server, in the Local Target Directory box of the VMDK Recovery Options frame, enter a valid path to the location for storing recovered images.
If this field is left blank, the default is the NetVault Backup “temp” directory (“…/NetVault Backup/tmp”).
3
If you want to restore the VMDK Image to a remote ESX Server, complete the following steps:
a
Select the Restore to Remote ESX Server check box in the VMDK Recovery Options frame.
b
Enter the values for ESX Host, Port, Username, Password, and Path.
These options are required to restore VMDK Images directly to an ESX Server. This step is useful when there is no local storage space on the NetVault Backup Server machine or when using ESX Server.
•
ESX Host: Enter the host name or IP address of the ESX Server.
•
Port: Enter the remote console port on the ESX Server.
•
Username: Enter the user name to log on to the ESX Server.
•
Password: Enter the password for the specified user name.
•
Path: Enter the directory on the ESX Server where the VMDK files should be created. This path should always start with a datastore within square brackets — [datastore] dir. If the path specified does not exist, the plug-in cannot connect to the ESX Server.
