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 and later are supported.

NOTE: The Hyper-V Agent for Windows Server 2012 R2 and older can do full backups of standalone servers or Hyper-V clusters. From Windows Server 2016 and newer the agent can do either full or incremental backups of the virtual machine (VM) disk.

Hyper-V Agent Set Creation

Launch the Backup wizard by selecting the Backup tab, and clicking "New."
Select the "Hyper-V Agent" and click "Next."
Enter the name of the Hyper-V Host server.

NOTE: Backup user must have administrative privileges on the Hyper-V server.

Select how you would like UltraBac to enumerate the Virtual Machines (VM's):

Enumerate all VM’s
Enumerate only powered on VMs
Enumerate only powered off VMs
Enumerate by VM name

Enter the name you wish to assign to the UltraBac set.

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: Microsoft has 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".

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).

Select the following options:

Virtual Machine (if there were multiple VMs backed up)
Hard disk
Volume

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:\).

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.
