Restore for Microsoft Hyper-V IntelliSnap

Choosing Restore Types

When restoring Hyper-V data, you can select one of the following restore type:

Full Virtual Machine

This restore type is selected by default. This restore type will be useful in the following scenario:

  • You are unable to turn on the virtual machine. However the disks (VHD files) are available for the machine

  • You want to restore an entire virtual machine to a specific point-in-time.

  • You want to move the virtual machine to a new Hyper-V host.

Virtual Machine Files

Use this restore type to restore disks (VHD files) from a virtual machine. This restore type will be useful in the following scenario:

  • The virtual machine is running, but one of its disk has errors.

  • The storage device hosting the disks has errors or not available.

    Note: File level browse and restore of 4K sectored disks is not supported.

Guest Files or Folders

Use this restore type to restore files or folders from a virtual machine.

This restore type will be useful in the following scenario:

  • A file or folder on the virtual machine has errors and you are unable to open the file or the folder.

  • You want to restore a file or a folder to a specific point-in-time.

Considerations

Restores cannot modify configuration files directly. For restores, the Virtual Server Agent imports the virtual machine from the backup and modifies the VM configuration after importing the VM (for example, attaching restored disks and reconfiguring networks). This type of restore is also supported for Windows Server 2012 R2 nodes.

Limitations

Microsoft Windows Server 2016 and Later Versions

  • For file-level restores or full VM restores from IntelliSnap backup operations, the proxy host that you designate for the restore operations cannot be a member of the cluster nodes where the source VM resides. To designate the proxy host (MediaAgent) for this scenario, follow these steps:

    1. From the CommCell Browser, go to Client Computers > Virtualization Client > Virtual Server > instance > DefaultBackupSet.

    2. Right-click the subclient, and then select Browse and Restore.

    3. The Browse and Restore Options dialog box appears.

    4. On the Advanced Options tab, from the Use MediaAgent list, select the MediaAgent.

  • Because of a Microsoft limitation, you cannot implement Disk Signature changes.

Live Browse Limitations

For information about Live Browse limitations, see Live Browse from IntelliSnap - Microsoft Hyper-V.

In-Place Restores

Restoring a Full Virtual Machine

  1. From the CommCell Browser, expand Client Computers > virtualization_client > Virtual Server >Hyper-V > backup_set.

  2. Start the restore from a subclient or backup set:

    • From the subclient, right-click the subclient and then select Browse and Restore.

    • From the backup set, right-click the backup set, point to All Tasks, and click Browse and Restore.

  3. In the Browse and Restore Options dialog box, ensure that Full Virtual Machine is selected, and then click View Content.

  4. From the list of backed up virtual machines, select one or more virtual machines that you want to restore, and then click Recover All Selected.

    The Restore VM wizard launches and displays the Destination page.

  5. Specify the destination and the proxy to be used for the restore.

    By default, VMs are restored in place to the original location for the source VM, and the restore is performed using the preferred VSA proxy for the virtualization client.

    • In Place: Clear this checkbox to restore out of place.

    • Virtualization Client: Displays the virtualization client for the source VM. To restore to a different Hyper-V environment, select a different virtualization client from the list.

    • Instance Details: Displays the user account for the selected virtualization client.

    • Destination Client: Displays the default VSA proxy for the restore. To use a different proxy, select a Hyper-V server from the list. Only proxies that match the type of the virtualization client are displayed.

      When a virtual machine is restored, it is automatically mounted to the Hyper-V Server of the specified destination client.

      If you are restoring to a CSV volume, select the client that owns the volume.

  6. Click Next.

    The wizard displays the Virtual Machines page. With an in-place restore no changes are required.

  7. Click Next.

    The wizard displays the Restore Options page.

  8. Optional: Select restore options:

Restoring Virtual Machine Files

Follow the steps given below to restore a disk from a virtual machine:

  1. From the CommCell Console, navigate to Client Computers > virtualization_client> Virtual Server > Hyper-V.

  2. Right-click the backup set that contains the data to restore and click All Tasks > Browse and Restore.

  3. In the Browse and Restore Options dialog, select Virtual Machine files and click View Content.

  4. Expand the listing in the Content tab and navigate to the required volume on a virtual machine.

    The right pane of the Content tab displays all the files in the volume.

  5. Select the required disks.

    You can select multiple disk files to restore. If you have created a checkpoint for the virtual machine, select any associated .avhdx files as well as the base disks.

  6. Click Recover All Selected.

  7. On the Restore Options for All Selected Items dialog:

    Option

    Steps

    Select a proxy:

    1. In the Destination client list, select the Hyper-V server that was used to back up the virtual machine.

    2. Specify the existing location of the disk in the Specify destination path box or click Browse to select a new location.

    Convert virtual machine disk:

    See Converting Virtual Machine Disks. If you select a disk to restore that is not in VHDX format, the conversion option is not presented.

    1. Under Virtual Disk Conversion, select the Convert Disk to option and use one of the following values:

      • VMDK: VMware virtual disk format. The VMDK disk is created with thick lazy zeroed provisioning. After conversion, you can attach the converted disk to an existing VMware virtual machine, or create a VMware virtual machine from the disk using vSphere.

      • VHD: Legacy virtual hard disk format for Hyper-V.

  8. Click OK.

Notes:

When you create a checkpoint for a virtual machine, an associated .avhdx file is created for the virtual machine disk. If you restore virtual disk files from such a backup, you must restore both the base (parent) disk and any associated .avhdx files (child disks). After restoring disk files, you can run the following PowerShell command to relink the parent and child files:

 
PS C:\> Set-VHD -Path child_disk.avhdx -parentpath parent_disk.vhdx -IgnoreIdMismatch

After running this command you can mount the disk and browse guest files on the virtual machine disk.

When you restore a virtual machine disk file, the permissions associated with the original virtual machine are not restored. As a result, you might not be able to start a VM that refers to the disk file. You can address this issue by removing and re-adding the disk to the VM, by using Hyper-V Manager to reset the correct security permissions, or by using the icacls command to restore permissions as described in Hyper-V virtual machine may not start, and you receive a “‘General access denied error’ (0x80070005)” error message.

Converting Virtual Machine Disks

As part of the process of restoring virtual machine disk files, you can convert disks to a new format:

  • VMware virtual machine disks in the VMDK format can be converted to VHD or VHDX.

  • Hyper-V disks in the VHDX format can be converted to VMDK or VHD.

After converting a disk, you can attach it to an existing VM or use it to create a new VM. Disk conversion can be used to move data from one platform to another, or as the first step in migrating a virtual machine from one platform to another.

Virtual machines created from converted disks can be backed up and restored using the same processes as virtual machines created directly in VMware or Hyper-V.

Considerations

  • Disk conversion is supported for both Windows and Linux VMs and for disks using thin or thick disk provisioning, and can be initiated from full or incremental backup jobs.

  • Disk conversion is not supported from differential backups, or for virtual machines with multiple snapshots.

  • You can initiate a disk conversion when performing a Browse and Restore operation on a subclient from a full, synthetic full, or incremental backup job.

    Note

    Instead of browsing a subclient, you can also view backup history and select a specific backup job to browse for a disk; but when using this method you can only initiate a disk conversion from a full or synthetic full backup job.

Guest Files and Folders

To restore files and folders to a Windows client, the client must have one of the following components installed:

  • Virtual Server Agent

  • Windows File System Agent (full or restore only)

You cannot restore files and folders directly to a Linux virtual machine. Instead, restore to another destination and copy the data to the virtual machine.

Considerations

  • The version of the file system agent on the destination VM must be the same as the version of the Virtual Server Agent.

  • For Windows:

    • You can perform the Browse and Restore operation by right-clicking a backup set. However, if the backup set contains some subclients configured for regular backup and other subclients configured for IntelliSnap backup, you must select the Browse and Restore option by right-clicking the subclient.

    • To live browse and restore files from an IntelliSnap backup of a Windows VM executed with a Linux MediaAgent, you must include the Windows MediaAgent information on the Advanced Options tab for the Browse request. This Windows MediaAgent cannot be a member of the cluster node, and it must be Hyper-V role enabled.

    • You can restore files from NTFS file systems with the following limitations:

      • The formatted cluster size (allocation unit) must be 1024 or greater.

      • You cannot restore any archived files and folders.

      • You cannot restore files that have been dehydrated by Windows 2012 dedup.

To live browse and restore files from an ReFS volume from a backup of a Windows 2016 VM, you must use a MediaAgent running on Windows 2016 or later.

  • Linux

    • The virtual machine must have the ext2 or ext3 file system.
Restoring Files and Folders

  13. On the Restore Options for All Selected Items dialog, click OK.

Out-of-Place Restores

Note

When a virtual machine is restored to a destination host that does not have the same names for virtual switches as the source host, the network adapter is not restored. The network connection is restored only if the same connection is available on the destination host at the time of the restore.

Before running an out-of-place restore, you can create a virtual switch on the destination host with a name that matches the virtual switch on the source Hyper-V host. Only use this approach if it is appropriate to use the same network connection for the virtual machine on the new host.

Otherwise, after the virtual machine is restored, manually connect the network adapter to a different virtual switch on the destination host.

Restoring a Virtual Machine to a Different Location

  1. From the CommCell Browser, expand Client Computers > virtualization_client > Virtual Server >Hyper-V > backup_set.

Manage Restore Jobs

Once you initiate the restore operation, a restore job is generated in the Job Controller. Jobs can be managed in a number of ways. The following sections provide information on the different job management options available:

Restart Jobs

Jobs that fail to complete successfully are automatically restarted based on the job restart configuration set in the Control Panel. This configuration can be changed at any time; but changes to this configuration affect all jobs run in the entire CommCell.

You can also override the default CommServe configuration for individual jobs by configuring retry settings when initiating the job. This configuration only applies to the specific job.

Note

Restore jobs for the Virtual Server Agent are restarted from the beginning.

Configure Job Restarts at the CommServe Level

  1. In the CommCell Console, click the Control Panel icon and then under Data, click Job Management.

  2. In the Job Restarts tab of the Job Management dialog, select a job type from the Job Type list, then select the Restartable option.

    • Kill Running Jobs When Total Running Time Expires - Option to kill the job when the specified Total Running Time has elapsed, even if its state is "Running".

  2. Click OK.

Resubmit Jobs

If a restore job fails to complete successfully, you can resubmit the job without the need to reconfigure the original job's restore options using the Resubmit Jobfeature. When a job is resubmitted, all the original options, restore destinations, and other settings configured for the job remain intact.

Resubmit a Restore Job

  4. Select the job options.

  5. Click OK.

Control Jobs

The following controls are available for running jobs in the Job Controller tab of the CommCell Console:

Suspend

Temporarily stops a job. A suspended job is not terminated; it can be restarted at a later time. Only preemptible jobs can be suspended.

Resume

Resumes a job and returns the status to Waiting, Pending, Queued, or Running, depending on the availability of resources or the state of the operation windows and activity control settings.

Restore jobs for the Virtual Server Agent are resumed from the beginning.

Kill

Terminates a job.

These controls can be applied to:

  • All jobs in the Job Controller.

  • All selected jobs in the Job Controller, providing you have security associations at the required level for each job selected.

  • All data protection operations running for a particular client, or for a client and agent.

  • All data protection operations running for a particular MediaAgent.

Control a Job

From the Job Controller tab of the CommCell Console, right-click the job and select Kill, Suspend, or Resume.

  • When killing a job:

    If you are sure you want to kill the job, click Yes on the confirmation prompt. The job status may change to Kill Pending for a few moments while the operation completes. Once completed, the job status changes to Killed; after five minutes the job is removed from the Job Controller window.

  • When suspending a job:

    The job status may change to Suspend Pending for a few moments while the operation completes. The job status then changes to Suspended.

  • When resuming a job:

    As the Job Manager attempts to restart the job, the job status changes to Waiting, Pending, or Running.

Data Path Options

Data Recovery operations use a specific data path (Library, MediaAgent, Drive Pool, and Drive) to perform restore operations as configured in the CommCell. By default, the system automatically identifies the data path for restore operations. You can change the data path in the Advanced Restore Options dialog by selecting a different MediaAgent, library, drive pool, or drive.

The following are some of the important situations where you may need to change the data path:

  • To free heavily loaded resources such as MediaAgents and libraries.

  • To move media to a different library after a library suffers severe hardware damage, in order to access data secured by data protection operations.

  • To assign a storage policy copy from a more active drive pool to a less active one, when one drive pool within a library is being used much more frequently than another.

  • From the CommCell Browser, click Client Computers | <VirtualizationClient> | Virtual Server | <InstanceName> | defaultBackupSet.

  • Right-click the subclient that contains the data to restore and select Browse and Restore.
