Hyper-V Agent

The UltraBac Hyper-V Agent provides users with the ability to back up virtual machines without installing any agents on those virtual machines. It also allows users to back up from one central location.

 

NOTE:  Only Hyper-V versions Windows Server 2008 R2, 2012, and 2012 R2 are supported.

 

NOTE:  For information on configuring deduplication server, please see the UltraBac Knowledge Base:

  1. Click "Action"/"Save Backup Set."

 

NOTE:  All backups must be saved to a local drive or a UNC share and the Hyper-V server must be able to access the share.

 

NOTE:  The Hyper-V Agent currently only supports MBR basic disks, not GPT basic disks, within the guest VM.

 

Microsoft has other conditions that must be met for the VSS backup of the guest VM to work:

 

  • Backup (volume snapshot) Integration Service is installed and running in the child VM. The service name is "Hyper-V Volume Shadow Copy Requestor".

Windows 2000:  Backup Integration Service is not supported.

  • The child VM must be in the running state.
  • The Snapshot File Location for the VM is set to be the same volume in the host operating system as the VHD files for the VM.
  • All volumes in the child VM are basic disks and there are no dynamic disks.
  • All disks in the child VM must use a file system that supports snapshots (for example, NTFS).

  1. Select the following options:

 

  1. Click the "Mount" button. This will mount the selected volume (VM disk) as a drive letter to the restore computer. From Windows Explorer on the restore computer, the files you want to restore can be drag and dropped from the mounted volume.

 

NOTE:  The VM disk will be assigned the highest drive letter available (i.e. z:\).

 

  1. Once complete, click the "Unmount All" button to unmount the VM Disk.

 

NOTE:  If the set or UltraBac is closed before the backup is unmounted, simply launch UltraBac Management Console and click on “Unmount All Volumes” located at “Tools”/“UBDR.” This will unmount any UltraBac mounted Image SFR, Hyper-V, or vSphere Agent backups. Alternatively, follow the same steps required to mount a backup until the "Unmount All" option button is visible.
