Restoring a Hyper-V

  • This article is for Windows only

Carbonite Server Backup (CSB) supports the following types of restores:

Hyper-V hosts and hosted virtual machines can be restored to the original location or to an alternate location.

  • All virtual machines may be restored using Restore All.
  • Individual virtual machines may be restored using Restore Select.
  • The Initial Store may be restored using Restore Select on Windows Server 2008 R2 and Windows Server 2012 R2.
    • The Initial Store cannot be restored in Windows Server 2012.
  • Files and folders within the backed up virtual machines can be restored.
    • Use the Files/Folders restore option to restore the virtual hard disks. These can be mounted to the file system and browsed for individual files and folders.
    • CSB will offer to mount the drives automatically.
    • For more information about restoring individual files and folders within a virtual machine, click here.

Restored virtual machines will be automatically imported into Hyper-V in most configurations. When restoring one or more virtual machines, all associated virtual hard disks will be restored.

Note: Ensure that the Restore Requirements are met before starting the restore. Additional requirements must be met for restoring files and folders.

Restore Requirements

The following requirements must be met, whether restoring to the original computer or to an alternate computer:

  • The amandabackup / CarboniteUser user must have full access to the folder where the backups are stored.
    • For cloud backups, this is the chosen Download Folder.
    • For local backups, this is the folder where the backups are stored on the local disk.
  • Likewise, the amandabackup / CarboniteUser user must have full access to the folder(s) to which the backups are being restored.

Additional Requirements for Restoring Files and Folders

CSB will offer to automatically mount a restored virtual hard disk file once the restore is complete. It will also ask if you want the mounted VHD to be displayed in Windows Explorer after the restore.

  • The operating system of the restore machine must be equal to or higher than the operating system of the machine where the backup was taken.
    • For example, a virtual hard disk that originated on a Windows Server 2012 system cannot be mounted to a Windows Server 2008 R2 system.
  • If every possible drive letter is already in use, the VHD cannot be automatically mounted. There must be free, non-reserved drive letters available.
  • The virtual hard disk must be using one of the following file systems to be automatically mounted.
    • FAT
    • FAT32
    • NTFS
    • ReFS, with some restrictions
      • ReFS disks can only be mounted on Windows Server 2012 and higher with the ReFS role enabled.
      • Additionally, the operating system version must match between the original system and the system performing the restore.
  • Dynamic disks cannot be mounted.

Managing VHD Files After the Restore

You can manage your VHD files from within CSB after the restore is complete. Simply right-click the Restore operation in the Report page. You will be presented with three options:

  • Mount VHD: Select this option to mount a VHD file. It is subject to the same requirements shown above.
  • Dismount VHD: Select this option to dismount a VHD file that is currently mounted.
  • Delete VHD: Select this option to delete the VHD file from disk.

CSB will not dismount the vhd files. You must dismount via the Report page, or do so manually using Disk Management or Powershell.

Further information about mounting and dismounting VHD files can be found in this Knowledge Base article.

Restoring to Original Location

CSB cannot overwrite an active, running virtual machine when restoring to the Original Location. If you attempt to do so, the restore will be interrupted with the following message:

The guest VM that you are trying to restore to appears to be in running state. It will be turned off during the restore.
Are you sure you want to continue?

Select OK to turn off the running VM and continue the restore. Select Cancel to abort the restore process.

  • The above warning will not appear if the name of the Virtual Machine has changed since the time the backup was performed. CSB will proceed directly with the restore and overwrite the existing VM.

Restoring to a Different Computer

You can restore your backed up data originating from one virtual machine to a different virtual machine. This method is mostly used to create a clone of the original system. It is recommended that you install the same Windows Operating System (with the same service packs) on the target virtual machine as was installed on the original virtual machine. This procedure requires additional steps that must be performed ahead of time. The steps are as follows:
