NetVault Bare Metal Recovery 12.5 - User Guide for Plug-ins

Using Plug-in Offline Client to restore data to a physical machine

This option lets you recover backups of the client to a physical machine that has the same hardware specification as the machine that was used for backup. It includes the following:

•

Prerequisites for restoring data with Plug-in Offline Client to a physical machine

•

Restore procedure for using Plug-in Offline Client to restore data to a physical machine

•

Post-restore for using Plug-in Offline Client to restore data to a physical machine


	CAUTION: Even if there is no difference between the system devices in a backup and a restore, the order of the disks might be different. If the restored data is started without performing a rename, any data that exists on the disks is lost. To compare the information of the physical disk at backup and restore, note the Disk Geometry and Device Size at backup. For more information, see Performing a restore in which Disk Numbers are different from the backup. For version 1.1.6 and later, also compare the Disk ID of the targeted disk on the Create Selection Set page to the Disk ID of the same disk on the NetVault Backup Selections page. Quest strongly recommends that you disconnect all disks that contain critical data from the server before you boot the Plug-in Offline Client.

Prerequisites for restoring data with Plug-in Offline Client to a physical machine

A DR restore procedure is a delicate operation. Before setting up and running a DR restore, the prerequisites covered in the following topics must be met.

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.


	IMPORTANT: When relocating a DR backup, ensure that the hard disk installed on the new relocation target has the same name as the hard disk that existed in the original target machine.

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 routine, 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

This information should have been noted before the backup — see Verifying Disk Geometry and Device Size. Have this information handy to complete the restore correctly.

Obtain new license key if reactivation is required (Windows only)

Sometimes, the restored Windows system might require reactivation. Verify that you have the necessary license key for reactivation.

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. To check access, perform the following steps.

With the NetVault Bare Metal Recovery Client booted with Plug-in Offline Client, access the NetVault Backup Server, and start the NetVault Backup WebUI.

Access the NetVault Backup Selections page to verify that the applicable client machine has been added as a NetVault Bare Metal Recovery Client.

Open the Plug-in Server to reveal existing clients.

Click the applicable NetVault Bare Metal Recovery Client, and select Edit from the context menu.

When the Edit Bare Metal Recovery Client dialog box is displayed, verify that the data is correct or change it as required.

If the NetVault Bare Metal Recovery Client is added correctly, skip to the Restore procedure for using Plug-in Offline Client to restore data to a physical machine topic; otherwise, proceed to the next step.

Add the applicable NetVault Bare Metal Recovery Client.

For detailed instructions, see Adding a NetVault Bare Metal Recovery Client to the Plug-in Server.

Continue to the Restore procedure for using Plug-in Offline Client to restore data to a physical machine topic.

Restore procedure for using Plug-in Offline Client to restore data to a physical machine

The procedure for restoring a DR restore to a physical machine includes the steps outlined in the following topics:

•

Selecting data for a restore

•

Setting restore options

•

Finalizing and submitting the job

Selecting data for a restore

In the Navigation pane of the NetVault Backup WebUI on the NetVault Backup Server, click Create Restore Job.

On the Create Restore Job — Choose Saveset page, select Plug-in Server from the Plugin Type list.

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 by creation date.

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, saveset size, and snapshot-based backup or not.

Click Next.

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

On the Create Selection Set page, click

, 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 Using Plug-in Offline Client to recover data 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.

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 option 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 Quest NetVault Backup Administrator’s Guide.

To save the settings, click Ok, and then click Next.

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 name 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.

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.

Use the Schedule, Source Options, and Advanced Options lists to configure any additional required options.

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 Quest NetVault Backup Administrator’s Guide.

NOTE: Be aware of the following items:

•

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 (P2V) recovery.

Post-restore for using Plug-in Offline Client to restore data to a physical machine

After restoring a backup to a different machine, review following points and take the applicable action:

•

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 9MAC), is different. If you use applications that rely on this address, work with the application’s vendor to address the change.
