Prerequisites for Hyper-V protection

The prerequisites for protecting Hyper-V environments are listed below. Additional requirements must be met for agent push installations and updates. See Agent push install requirements and Requirements for pushing agent updates for details.

Description

Hyper-V hosts supported

For supported hosts, see the Unitrends Compatibility and Interoperability Matrix.

Unitrends system version

Release 6.2.0 and higher

Unitrends Windows agent version

The Hyper-V agent is included in the Unitrends Windows agent release 6.2.0 and higher. No additional installation packages or licenses are required for protecting virtual machines in a Hyper-V environment.

Microsoft VSS

Microsoft’s Volume Shadow Copy Service (VSS) and the Hyper-V VSS writer must be installed and running on the Hyper-V host.

Virtual machine configuration

Hyper-V backups do not support VMs configured with pass-through disks. To protect a VM with pass-through disks, install the appropriate agent in the guest operating system, add the VM to the backup system as you would add a physical machine, and protect it with the appropriate file-level and application backups. Protect the VM’s operating system using Untirends bare metal protection. For details, see Backups Overview.

Online backups of a virtual machine

To perform online backups of a virtual machine, you must install Integration Services in the guest operating system. Integration Services enable the virtual machine to create a child state snapshot. The host can then use this snapshot to perform an online backup of the virtual machine. To determine which guest operating systems support Integration Services and online backups, refer to the Microsoft document Hyper-V Overview.
