NetVault Plug-in for Hyper-V 12.2 - User Guide

Introducing NetVault Backup Plug-in for Hyper-V Installing or removing the plug-in Configuring the plug-in Backing up data Restoring data Troubleshooting

Setting image-level restore options

If you are restoring a backup that was created using an earlier version of the plug-in, complete the steps outlined in the user's guide for the corresponding version; this section only applies to the current version of the plug-in.

1
On the Create Selection Set page, click Edit Plugin Options.
2
Select one of the following parameters:
•
To restore the entire VM and establish a new version of that VM in Hyper‑V Manager, select Recover entire VM to host and/or cluster.
•
To restore specific files to a location specified by you, select Restore files from inside VM guest OS to specified location.
 
* 
CAUTION: The Delete working directory contents after recovery option is selected by default. Do not clear this option unless instructed to do so by Quest support.
3
If you selected the Recover entire VM to host and/or cluster option and you want the recovered VM to be restarted automatically, select the Power-on VM after recovery option.
 
* 
NOTE: The Power-on VM after recovery option is only available if you select a backup saveset that was created using version 11.4 or later of the plug-in.

Finalizing and submitting an image-level restore 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.

1
To save the settings, click Ok, and then click Next.
2
In Job Name, specify a name for the job if you do not want to use the default setting.
Specify a detailed title that lets you easily identify the job when monitoring its progress. The job name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. 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.
If you select a Virtual Client, the plug-in restores the VM to the host that is managing the cluster.
 
* 
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 Quest NetVault Backup Administrator’s Guide.
 
* 
NOTE: If you restore a saveset that was created with Plug‑in for Hyper‑V version 10.5 or earlier, the Virtual Hard Disk (VHD or VHDX) files are stored in <installationDirectory>\tmp\Hyper-V.

If your environment uses Windows Server 2008 R2 and the original VM included network adapters, use Hyper-V Manager to add the network adapters.

Performing file-level recovery

If you select the Enable indexing for File Level Recovery option during backups generated using version 10.5 or later of the plug-in, you can restore individual files and directories from an image-level backup. The process includes the steps outlined in the following topics:

•
Selecting data for a file-level restore
•
Setting file-level restore options
•
Finalizing and submitting a file-level restore job
 
* 
IMPORTANT: The plug-in does not support file-level restores of compressed or sparse Windows Server NTFS files, Linux sparse files, or files that reside on VMs using Storage Spaces.

You can only select one VM at a time for a file-level restore job. To recover files from more VMs, run more file-level restore jobs.

Selecting data for a file-level restore

1
In the Navigation pane, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select Plug‑in for Hyper‑V 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 by creation date.
4
In the saveset table, 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.
 
* 
IMPORTANT: If your restore job includes a Linux VM, the Enable indexing for File Level Recovery option was selected during backup, the VM contains two files in the same directory that use the same name — differentiated only by capitalization — and you must restore both files, create and run two restore jobs. In one job, include all applicable files and one of the files with the same name. In the other job, include only the other file that uses the same name, and specify a different location for the restore. Because Windows is not case-sensitive, it does not recognize the distinction between the two files; this workaround prevents the restore from completing with warnings and ensures that both versions of the file are recovered.
5
Click Next.
6
On the Create Selection Set page, expand the Volumes node to display the indexed partitions, directories, and files contained within, and then select one or more indexed items for the restore.
 
* 
IMPORTANT: Select only the applicable folders or files, or both, located under the Volumes node. Do not select the VM node itself.

Do not use the Rename option in the context menu. Although the option is displayed, the plug-in ignores the Rename field and the restore completes with warnings.
