NetVault Plug-in for Hyper-V 12.0 - 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

Restoring image-level backups

You can perform an image-level recovery, which restores the entire VM and establishes a new version of that VM in Hyper‑V Manager. The process restores files either to their original location or to a location specified by you when you create a selection set and enter information in the Rename/Relocate dialog box. For instructions on performing restores from a previous version of the plug-in, see the user's guide for the corresponding version.

 
* 
IMPORTANT: The plug-in flattens Hyper-V checkpoints when a backup is taken and later retrieved using an image-level recovery process. For example, if you back up a base disk that has two checkpoint files that the VM is running, the VM is restored with only one base disk; however, all content from the checkpoint files is included.

This process includes the steps outlined in the following topics:

•
Prerequisites for image-level restore
•
Selecting data for an image-level restore
•
Setting image-level restore options
•
Finalizing and submitting an image-level restore job

Prerequisites for image-level restore

Verify that the following prerequisites are met:

•
If you do not intend to use the Rename feature, Quest recommends that you delete the original VM before you perform recovery.
•
If you do not intend to use the Rename feature and you do not intend to delete the original VM, ensure that the VM is turned off. Also ensure that none of its files are open before you perform recovery. The plug-in’s recovery process overwrites the existing VM, and write-access is required.
•
Before recovering a VM to different host, verify that the VM resources in the Configuration File match the resources available on the host. In particular, verify that file locations and network-adapter names match. If they do not match, the VM might not get turned on. If resources are different on the target host, complete the recovery manually.

Selecting data for an image-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.
5
Click Next.
6
On the Create Selection Set page, select the localhost or <clusterName> node to display the VMs, and then select one or more VMs to restore.
 
* 
NOTE: You cannot select individual files under a VM node. If you enabled indexing during backup and want to restore individual files, use file-level recovery. For more information, see Performing file-level recovery.

If you select an Incremental or Differential Backup, the plug-in automatically restores all savesets in the backup sequence up to the selected saveset.

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.
