Bare Metal Restore

Bare Metal Restore (BMR) allows you to apply an entire system image to new or existing devices. Rather than spending time and resources to rebuild an entire device from scratch, you can quickly restore entire system data from any successful recovery point.

As a first step, you will need to lock the system image for the BMR process.

  1. In the UMC Dashboard of the appliance protecting the desired device, click the Virtual Machine & BMR tab.

  2. Click the Control button next to the appropriate device.

  3. In the Bare Metal Restore drop-down menu, click Start.

  4. Select the recovery point and click the Start BMR button. You have now locked the system image for the BMR process.

The BMR Recovery Disk

To start the process, you can access one of the BMR ISO versions from the Axcient site:


  • BMR x86 ISO

When you have determined which BMR ISO is required, download the BMR ISO and burn it onto a bootable media compatible with the physical device.

When the BMR ISO has been burned onto a bootable media, connect it to the target device and boot from it.

Loading Additional Drivers

As part of the BMR process, common drivers are automatically loaded onto the target device. However, the target device might also require additional drivers to function properly. For example, you might need drivers that detect RAID devices.

Before beginning the BMR process, you should determine if additional drivers need to be loaded onto the device.

  1. When the device has booted from the bootable media, a Start BMR screen displays, prompting you to select from the following options:

    • Reboot allows you to reboot the device.

    • DOS opens a DOS window where you can issue commands such as diskpart, chkdsk, and so forth.

    • Load Drivers allows you to load drivers for the BMR ISO. For example, this can be used to load drivers to detect RAID devices on the target device.

    • Sys Info provides information used by Axcient Support to help troubleshoot problems.

    Select the Load Drivers option to load the drivers.



    Before beginning the BMR process, we strongly recommend downloading any additional drivers required for the BMR process to complete successfully. Any drivers that will detect devices on the target machine should be downloaded before beginning the BMR.

  2. After selecting the Load Drivers option, you will be presented with a list of drivers that are required for the BMR process to complete successfully.

    Refer to the Device Status column to determine which drivers have already been included and which drivers need to be installed.

    To load drivers, click the Load Drivers button.

  3. If you selected the Load Drivers option, the Load Additional Drivers screen displays.

    Click the Browse button to browse and select the folder containing the appropriate drivers.

  4. Click the Choose button to select a folder, and then click the Load button.

    The BMR ISO will automatically scan the folder and load any drivers available. Repeat this step as many times as necessary.

    When the necessary drivers have been selected, return to the initial Start BMR screen.

Performing the BMR
  1. After all drivers have been loaded, and you have performed any required DOS commands, click the Start BMR button to begin the BMR process.

  2. In the next screen, you will be presented with a list of tasks that must be completed before beginning the BMR process. Failure to verify one or more of these conditions might cause the BMR process to fail.

    If performing a BMR from a production failover, do not discard the failover VMs. Instead, select the Stop button in the production failover VM to stop and not discard the VMs.

    Click the Next button to continue.

  3. In the next screen, verify the WinPE IP address. The WinPE uses a temporary IP address to perform the BMR. This IP address is for the BMR only and will not be the final IP address of the device being restored.

    • Click the Renew DHCP button to automatically assign an IP address to the WinPE.

    • Click the Set Static IP button to manually configure the IP address.

    If you do not see an IP address on this screen, you will need to load the appropriate NIC drivers.

    When the IP address has been configured, click the Next button.

  4. In the next screen, enter the following information for the appliance protecting the device being restore:

    • IP Address of the appliance

    • Username

    • Password

    When you are finished, click the Next button.

  5. In the next screen, select the device being recovered. Only one device can be selected. When are you finished, click the Next button.

  6. In the next screen, select the date of the appropriate recovery point and click the Choose button.

  7. In the next screen, you will be presented with a list of the replicated drives from the selected device restore point. You can select to exclude one or more drives from the BMR process. You cannot exclude the boot drive for the OS. Click the Next button to continue.

  8. In the next screen, configure the disk partition schema. These fields are automatically populated with recommended settings. You might notice SYS, MSR or EFI in one or more of the partitions. These are reserved partitions needed to boot the target device. The top section lists each detected volume. Use this section to update key settings:

    1. In the Disk column, use the drop-down menu to assign a disk to a specific driver letter.

    2. In the Total Size column, configure the size of the partition. Each partition, as well as the sum of all partitions, cannot be larger than the total disk size.

    3. If you do not see any drives, or if a drive is missing, click the Load Drivers button to browse and load the appropriate drivers that will detect the missing drives.

    4. When you are finished, click the Next button.

  9. In the Running BMR screen, you can track the BMR process with:

    • The progress bar,

    • The total completion percentage,

    • The drive currently being restored, and

    • GB processed out of the total GB to be processed.

  10. When the BMR process completes successfully, click the Next button.

  11. In the next screen, configure the network information of the restored device. You can select from the following options:

    • Recovery Point network settings allow you to use the network settings of the selected restore point.

    • Assign IP using DHCP allows you to use a new IP address for the restored device after the BMR process completes and the device is rebooted.

    • Set static IP address allows you to manually configure the network settings for the restored device.

    Click the Next button when you are finished.

  12. In the next screen, review the list of drivers for the target device. Click the Load Drivers button to browse and load the required drivers. Please note that not all drivers are required to be downloaded in order to boot the device after the BMR process. However, if you experience boot issues, please refer to the Troubleshooting Boot Errors section of this guide for more information. When the boot-critical drivers have been installed, click the Next button.

  13. When the BMR process has completed successfully, click the Reboot Machine button to reboot the target device. Disconnect the bootable media containing the BMR ISO so that the device does not boot from the bootable media when restarting.

Troubleshooting Boot Errors

If you are unable to start the target device after the BMR process completes, you should ensure that all necessary drivers have been added.

To confirm all necessary drivers have been added:

  1. Reconnect the bootable media containing the BMR ISO to the target device and boot from the media.

  2. In the Start BMR screen, click the Load Drivers for Image Backup option.

  3. Follow the steps listed above to load any additional drivers needed for the device to function properly.

Discarding the Image Lock

When the BMR has successfully completed, you must discard the image lock on the device. If you do not remove the system image lock, backups will not continue to run on the device.

  1. On the UMC Dashboard, click the Virtual Machines & BMR tab.

  2. Click the Control button to view the lock for the BMR.

  3. In the Bare Metal Restore drop-down menu, click Stop.

  4. On the confirmation screen, click the Done with BMR button to discard the system image lock.

Bare Metal Recovery Appendix

Axcient BMR versions newer than 3.0 use UEFI boot method for OS installation on the target server. Older server models do not support this boot method so the BMR process will fail with these servers.

If you are recovering an older server model that does not support the UEFI boot method, you can force BMR to use the standard boot method by following the instructions below.


The instructions listed below assume the target disk is clean and empty and that the target disk is "disk 0" in diskpart.

  1. Boot into the BMR 3.2.3 and install all the drivers so the network and HDDs are operable. Please note that you are not ready to proceed to the BDR process.

  2. Next, open a DOS window and start diskpart.

  3. Select the disk and clean everything as a precaution.

    sel disk 0
  4. Create a 100 MB partition as a precaution.

    create partition primary size=100
    format quick fs=fat32 label="System"
  5. Create a partition for Drive C (Windows). The size is listed in MBs. You must make this partition active. For example:

    create partition primary size=40000
    format quick fs=ntfs label="Windows"
  6. Create a partition for each of the other drives. For example:

    create partition primary size=10000
    format quick fs=ntfs label="ntfs"

    If you hit a primary partition limit, create extended partitions.

  7. Ensure everything is correct and then exit diskpart. Please note that you do not need to assign any drive letters.

    list vol
  8. Close the DOS window and start the BMR process. When prompted to select a partition, select Use existing partition structure.

  9. Ensure all drives are in the correct order. Start the BMR process and wait for completion. You must inject RAID drivers if needed. Reboot the machine when the process is complete.
