Restoring a raw device backup

The procedure for restoring a Raw Device Backup includes the following steps:

•
Prerequisites
•
Restore Procedure

Prerequisites

Before you start the restore procedure, verify that the following requirements are met:

•
Restore an entire disk: Unmount the target disk. Verify that the size of the target disk is equal to or larger than the size of the source disk.
•
Restore an individual partition: On Windows, verify that the size of the target partition is equal to the size of the source partition. When you restore the data to a partition of a different size, the job completes with the message “Partition to Restore to a Different Size than the Backed Up Partition.” This type of restore might require reinstallation or reformatting.
This requirement does not apply to Linux and UNIX systems.
 
* 
NOTE: The Plug-in for Raw Devices cannot be used to perform cross-platform restores. You cannot restore raw device backups of a Windows Client to a Linux Client or raw device backups of a Linux Client to a Windows Client.

Restore Procedure

To restore a raw device backup:
1
In the Navigation pane, click Create Restore Job. Complete Step 1 through Step 2 in the section Restore Procedure.
2
On the Create Selection Set page, select the disks that you want to restore. Alternatively, open the parent node and select the partitions that you want to restore.
Click Save to save the settings, and then click Next.
3
On the Create Restore Job page, specify a name for the job. Assign a descriptive name that allows you to easily identify the job for monitoring its progress.
A job name can contain alphanumeric and non-alphanumeric characters, but it cannot contain non-Latin characters. There is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
4
In the Target Client list, the client from which data was backed up is selected by default. Do not change this setting.
5
Select or create the Schedule Set, Restore Source Set, and Advanced Options Set. For more information about these sets, see the Quest NetVault Administrator’s Guide.
6
Click Submit to submit the job for scheduling.
 
* 
IMPORTANT:  
•
While restore is in progress, do not access the target drive. If you do so, the job fails and the partition data is corrupted.
•
To view the job status, use the NetVault WebUI.
•
After a restore completes on a Windows Client, reboot that machine. Do not try to view or browse the restored data until the machine is rebooted.
Additional notes

If you select MBR and one or more partitions for a restore job, the plug-in restores the MBR successfully, but it fails to restore the selected partitions and the jobs completes with warnings (“Failed to get the information of Partition <n> for Disk <n>”). The plug-in is unable to obtain the partition information because the information about the restored MBR has not been updated on Windows.

To restore MBR and one or more partitions, use the following steps:

1
Restore the MBR.
2
Start the Windows Disk Management utility. Use the Refresh command to update the MBR information on Windows.
3
Restore the individual partitions.

Relocating data to an alternate disk or partition

To restore a Raw Device Backup without overwriting the existing data, you can relocate the data to an alternate disk or partition on the client. You can also use this procedure if the original disk is unavailable or corrupted.

 
* 
IMPORTANT:  
•
On Windows, you can restore the MBR to an alternate disk without recreating the individual partitions.
•
You can relocate the MBR to any disk, but it must be copied to partition zero on that disk.
•
You can relocate a backup to a designated disk or partition using the disk and partition numbers.
To relocate data to an alternate disk or partition:
1
Start the restore wizard, and select the data that you want to restore. For more information, see steps 1 through 3 in the section Restoring a raw device backup.
2
Select the disk or partition that you want to rename or relocate and click Rename.
3
In the Rename/Relocate dialog box, provide the following information.
•
Linux and UNIX: Type the full path to the new disk.
•
Windows: To relocate the data to an alternate disk, type the target disk number. For example, Disk 1 or 1.
To relocate the data to an alternate partition, type the disk number and the partition number. For example, Disk 1 Partition 4 or 1 4.
Click OK to close the dialog box.
After you close the dialog box, the plug-in updates the corresponding node in the selections tree to display the new location for the disk or partition.
4
Complete steps 3 through 7 in the section Restoring a raw device backup.
