How to Restore a Windows System to Bare Metal

  • Last updated on

This article refers to the Barracuda Backup Legacy Release firmware or newer, except where noted.

Bare metal recovery allows you to restore a complete Microsoft Windows system, including data, settings, applications, and operating system, onto a new computer on which nothing is installed.

The bare metal recovery process overwrites all existing data on the system to which you are restoring the data; therefore, bare metal recovery is recommended
only when no other recovery option is available. This process rebuilds the target computer or server to its original system setup.

A bare metal restore is intended to be used for restoring to similar hardware.

All system volumes and system state must be backed up in order for bare metal recovery to be possible.


You must have an existing backup of a system that uses one of the following Microsoft operating systems:

  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2012 R2
  • Microsoft Windows Server 2012
  • Microsoft Windows Server 2008 R2
  • Windows 2008 Server
  • Windows Small Business Server 2011
  • Windows Small Business Server 2008
  • Windows Vista
  • Windows 10
  • Windows 8
  • Windows 7

Additionally, you must have all of the following:

  • Barracuda Backup Server firmware version 6.1 or higher;
  • Barracuda Backup Bare Metal Live CD 6.1 or higher (available from the System > Software Downloads page); and
  • Administrator rights to the Microsoft Exchange Server.

Bare Metal Live CD

Use the following steps to download the Bare Metal Live CD boot media; select the appropriate bit version for the OS you are planning to restore. For example, if you are restoring a 64-bit operating system, you must use the 64-bit version.

  1. Log in to Barracuda Backup and go to System > Software Downloads. Download the Bare Metal Live ISO file to your local system.
  2. Burn the Bare Metal Live ISO file to a CD.
  3. Boot the system you want to restore using the Bare Metal Live CD you created in step 2.
  4. Read the onscreen warning:
  5. To continue with the Bare Metal restore, click Next.
  6. Set up the Network configuration:
    • If you have DHCP enabled on your network, an assigned IP address displays in the IP Address field.
    • If DHCP is not enabled, clear DHCP, and enter the IP AddressSubnet Mask, and Default Gateway:
  7. Click NextYou are prompted to log in to Barracuda Backup:
  8. In the Barracuda Backup web interface, go to the Restore > Restore Browser page and select the system you want to recover.
  9. Click View all revisions up to: <date> to view the selected system's revisions available for restore:
  10. In the Revisions list, click Restore for the revision you want to recover.
  11. In the Restore dialog box, click the Restore tab, and enter the IP address of the system you are recovering in the Restore to section:
  12. Click Start Restore.
  13. For the system booted using the Bare Metal Live CD, a list of volumes that are recoverable displays:

  14. Select the volumes you want to recover.

    You cannot deselect boot and system volumes as these 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.

  15. (Firmware version 6.3.02 and higher only) You are presented with the option to select which disks you want to include/exclude when determining disk repartition. To exclude a destination disk, clear the checkbox next to the disk name:

    1. Click Yes to confirm your selection:

    2. An additional warning displays; click Yes if you want to proceed:

  16. Click Next to begin the restore:
  17. When the restore is complete, click OK in the Confirmation dialog box. 
  18. Remove the bare Metal Live CD, and reboot the system.

SQL, Exchange Server, and Hyper-V Host
If SQL, Exchange Server, and/or a Hyper-V Host are installed on the system, you must restore those items separately once the bare metal restore is complete.
