Restoring virtual machine disk and configuration files

The procedure for restoring virtual machine disk and configuration files from an image-level backup includes the steps outlined in the following sections:
•
Restoring data
•
Recovering a virtual machine from the restored files

Restoring data

To restore virtual machine disk and configuration files
1
In the Navigation pane, click Create Restore Job.
2
IIn the saveset table, select the saveset that you want to use, and click Next.
The table displays the saveset name (Job Title and Saveset ID), creation date and time, and saveset size. Note the following:
•
The list is sorted alphabetically by saveset name. You can sort the list by a different column or reverse the sort order by clicking the column heading. The arrowhead next to the column name indicates the sort order.
•
You can use one or more filters to display specific savesets on this page. You can also search for a data item in savesets and view the media list for a saveset. For more information about the additional features, see Using additional features available on the Choose Saveset page.
•
When you select a saveset, the following details are displayed in the Saveset Information area: Job ID, Job Title, name of the NetVault Backup Server, name of the client from which the data was backed up, plug‑in used to create the saveset, saveset creation date and time, saveset retirement setting, whether Incremental Backup or not, whether Archive or not, and saveset size.
3
On the Create Selection Set page, select the image from which you want to restore the disk and configuration files.
4
Click Edit Plugin Options, and in the Plug-in for VMware Restore Options dialog box, configure the following settings.
 
Table 6. Options for restoring virtual machine disk and configuration files from image-level backups
Option
Description
Restore Files from Backup
To perform file-level restores from image-level backups, select this option.
NOTE: After selecting the individual files and directories under the Volumes node, if you do not select this option, the job fails.
Target Directory
Type the full path to the directory to which you want to restore the virtual machine disk and configuration files. The target directory must be local to the NetVault Backup Client on which the Plug‑in for VMware is running. Currently, mapped network drives, mounted network shares, and UNC paths are not supported.
The plug-in does not check if you have specified a local or remote directory. If plug-in cannot access the specified path, the job fails.
Split Restored Virtual Disks
This option can be used when restoring virtual disk files to the local file system. If the check box is selected, the plug-in splits the “.vmdk” file into 2GiB files. If you clear the check box, the plug-in restores the “.vmdk” file is as a single disk file.
This option is only available to backups created using Plug‑in for VMware 10.0.5 and later. To force this behavior when restoring a backup created using Plug‑in for VMware 10.0.1 or an older version, configure this option in the vmware.cfg file:
1
Open the vmware.cfg file in any text editor. You can find this file in <NetVault Backup home>\config on Windows and <NetVault Backup home>/config on Linux.
2
Add the following lines:
[Custom:RestoreSplitVMDK]
Value=TRUE
3
Save the file.
The setting for this option in the Plug-in for VMware Restore Options dialog box overrides the setting in the vmware.cfg file.
5
Click Save to save the settings, and then click Next.
6
In Job Name, specify a name for the job.
Assign a descriptive name that allows you to easily identify the job for monitoring its progress. The 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
7
In the Target Client list, the client from which data was backed up is selected by default. Do not change this setting.
8
Select or create the Schedule Set, Restore Source Set, and Advanced Options Set. For more information about these sets, see the Dell NetVault Backup Administrator’s Guide.
9
Click Submit to submit the job for scheduling.
10
You can monitor the job progress from the Job Status page and view the logs from the View Logs page. For more information about these functions, see the Dell NetVault Backup Administrator’s Guide.

Recovering a virtual machine from the restored files

After restoring the virtual machine disk and configuration files, you can use the VMware vCenter Converter Standalone Client to create a virtual machine using the restored “.vmx” and “.vmdk” files. After a VADP Recovery, you must modify the “.vmx” file so that it matches the disk paths of the restored “.vmdk” files. For more information, see the relevant VMware vCenter Converter Standalone Client documentation.
Recovering a virtual machine from a VCB backup
To restore the virtual machine files to the destination VMware Server, start the VMware vCenter Converter Standalone Client Wizard. Follow the instructions to complete the virtual machine recovery. When the prompt “Select source type” prompt appears, select the option “Backup image or third-party virtual machine.” Additionally, set the “Virtual machine file” option to the restored “.vmx” file.
Recovering a virtual machine from a VADP backup using vCenter Converter
To recover the virtual machine, you must edit the “.vmx” file, and change the datastore path to reflect the restored “.vmdk” files.
To change the datastore path
1
Navigate to the target directory to which the virtual machine files were restored and note the filenames of the virtual disks.
The following example shows some files generated from Virtual Machine Files Only Restore of a VADP backup:
MyVirtualMachine.vmx
scsi0-0-MyVirtualMachine.vmdk
scsi0-0-MyVirtualMachine-s001.vmdk
VirtualMachineConfigInfo
2
Open the “.vmx” file.
3
Modify the relevant entries for the virtual disk(s).
For example, modify the following entry:
scsi0:0.fileName = “MyVirtualMachine-000001.vmdk”
It must match the “.vmdk” file generated during restore.
scsi0:0.fileName = “scsi0-0-MyVirtualMachine.vmdk”
4
After modifying the “.vmx” file, start the VMware vCenter Converter Standalone Client Wizard to create the virtual machine. Follow the instructions to complete the virtual machine recovery. When the “Select source type” prompt appears, select “VMware Workstation or other VMware virtual machine.” Additionally, set the “Virtual machine file” option to the restored “.vmx” file.
 
 
*NOTE: In the scenario described in the article http://kb.vmware.com/kb/1019286, the “.vmx” file is not backed up, but the “.vmdk” files are available.
