Physical-to-Virtual Recovery

  • Last updated on

You can use the physical-to-virtual recovery (P2V) method to recover entire physical Microsoft Windows systems to a VMware or Hyper-V environment in the event the system has completely failed and no other recovery options are available. With P2V, all data, settings, applications, and operating system are installed to a VMware or Hyper-V system with no operating system installed.

To perform a P2V, all system volumes and the system state must be backed up on the data source. P2V requires that the target virtual system is configured with similar virtual hardware to the originally backed up physical system (source).

Windows 2016 and 2019 ReFS partitions are currently not supported in a physical-to-virtual restore.

Install the Windows ADK and Windows PE Add-On

The Barracuda Backup Bare Metal Recovery (BMR) kit is used to create a bootable ISO based on WinPE. This enables you to perform a physical-to-physical (P2P) or physical-to-virtual (P2V) bare metal restore of your Microsoft Windows Server, without installing an operating system first.

Before you can build a BMR ISO, you must install the Windows ADK and the Windows PE add-on for the ADK.  The scripts included in the Barracuda Backup BMR Kit uses this software to generate an ISO used for bare metal recovery.

The following files are required to build the BMR ISO:

  • From Microsoft:
    • The latest Windows ADK
    • The latest Windows PE add-on for the ADK
  • From Barracuda:
    • The Barracuda Backup Bare Metal Recovery Kit. Within Barracuda Backup, navigate to the System > Software Downloads page and download from the Windows Bare Metal Recovery Kit section.

Download the latest Windows ADK and Windows PE add-on for the ADK from Microsoft (https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install).



Install the Windows ADK
  1. Run adksetup.exe to install the Windows ADK.
  2. Select Install the Windows Assessment and Deployment Kit - Windows 10 to this computer using the default Install Path . Click Next.
  3. Specify whether you want to send your usage data to Microsoft. Click Next.
  4. Click Accept to accept the license agreement.
  5. Keep the default feature settings and click Install
  6. After the installation has completed successfully, uncheck the Launch the Getting Started Guide check box. Click Close.
Install the Windows PE Add-On for ADK
  1. Run adkwinsetup.exe to install the Windows PE add-on for the ADK.
  2. Select  Install the Windows Assessment and Deployment Kit Windows Preinstallation Environment Add-ons - Windows 10 to this computer using the default Install Path . Click Next.
  3. Specify whether you want to send your usage data to Microsoft. Click  Next .
  4. Click Accept to accept the license agreement.
  5. Keep the default feature settings and click Install
  6. After the installation has completed successfully, click Close.

Download and Extract the Barracuda Backup BMR Kit

  1. Within Barracuda Backup, navigate to the  System > Software Downloads  page and download the  Barracuda Backup Bare Metal Recovery Kit .
  2. Unzip the BarracudaBackupBmrKit-X.Y.ZZ.zip archive file. Note the location of the extracted folder.
  3. Open a command prompt and navigate to the BarracudaBackupBmrKit folder where you extracted the archive in Step 2.
  4. Run the  create_bmr_iso.bat  script with the following commands that correspond to the ISO you want to create.
    • 64-bit ISO without additional drivers: create_bmr_iso.bat amd64 C:\winpe-workspace C:\bmr.iso
    • 64-bit ISO with additional drivers: create_bmr_iso.bat amd64 C:\winpe-workspace C:\bmr.iso C:\drivers-for-bmr

    • 32-bit ISO without additional drivers: create_bmr_iso.bat x86 C:\winpe-workspace C:\bmr.iso
    • 32-bit ISO with additional drivers:  create_bmr_iso.bat x86 C:\winpe-workspace C:\bmr.iso C:\drivers-for-bmr

    Note that it will take several minutes for the script to build the BMR ISO.
  5. Delete the directory you specified as the workspace (e.g. C:\winpe-workspace).

Prepare the Virtual Target

Before starting the restore, you must configure the system firmware option—BIOS or Extensible Firmware Interface (EFI)—on the target virtual system to match the original physical system (source). When you select a guest operating system, BIOS or EFI is selected by default, depending on the firmware supported by the operating system. If the operating system supports BIOS and EFI, you can change the default from the Options tab of the Virtual Machine Properties editor after you create the VM and before you install the guest operating system. If you select EFI, you cannot boot an operating system that supports only BIOS, and the reverse.

When creating the target VM in VMware or Hyper-V, use the same operating system architecture and configuration as the physical target system. For example, use the same CPU (x86 or x64), RAM, and disk configuration.

Perform Physical-to-Virtual Recovery

You must complete all of the steps described in the sections above, including downloading and installing Windows ADK and Windows PE add-on for ADK.

To perform a bare metal recovery:

  1. Use the Bare Metal Recovery ISO file you created above to boot the target system.
  2. After the target system boots, the Bare Metal Restore Utility welcome/warning screen displays. Ensure that no data is present on the target system. Click Next.
  3. On the Network Configuration screen, choose a N etwork Interface, and specify an IP AddressSubnet Mask, and Default Gateway. Then click Next.
  4. The Awaiting connection screen displays.
  5. Log into the Barracuda Backup local or cloud interface, and go to the Restore > Restore Browser page.
  6. Click Restore to the right of the Microsoft Windows system you want to restore. If you want to restore to a different backup revision of the system other than the latest, click on the system, and click View all revisions up to: <date> , and click Restore next to the backup revision.
  7. In the Restore dialog box, select Other Hostname or IP Address, and type the IP Address configured for the target system in the Bare Metal Restore Utility. Select Destination is a VMware or Hyper-V guest.
  8. Click Start Restore.
  9. After several minutes, the target system receives the restore job from Barracuda Backup and displays a list of recoverable volumes.

  10. Select the volumes you want to recover. Click Next.

    You cannot deselect boot and system volumes because they are required for the bare metal restore.

    If you choose to restore to a server that does not have identical volumes as the original machine the data was backed up from, the Barracuda Backup appliance will still attempt to restore all drives even though you may have only selected one of these on the Bare Metal Restore screen. The restore will throw errors for these missing drives, but will restore the drives that exist on the target machine.

  11. Select which disks on the target VM will be used in the recovery operation.

  12. Click Next, then click Yes to confirm your selection.

  13. An additional warning displays.
  14. Click Yes to proceed. Click Next to begin the system restore.

  15. When the restore is complete, click OK in the Confirmation dialog box.

  16. Remove the Bare Metal Recovery ISO and reboot the system.

    If the server being restored was an Exchange, SQL, or Hyper-V server, the application is installed after the bare metal restore. The databases or guest virtual machines (VMs) must be restored separately.
