Version: DPX 4.16

Hyper-V Backup

Catalogic Software provides DPX Block and Agentless data protection for virtualization to protect Microsoft Hyper-V environments. For block data protection, the DPX agent must be installed on each guest virtual machine that is protected by DPX. Both hosts and clusters are supported.

To use the Agentless Backup for Microsoft Hyper-V, you must install Catalogic DPX Backup Agent for Microsoft Hyper-V on your Microsoft Hyper-V host. The agent handles Hyper-V snapshot processing and communicates with the storage destination and master server. Agentless Hyper-V Backup supports auto-discovery and protection of new and modified VMs. Moreover, it supports crash-consistent backup of all guest operating systems supported by Microsoft Windows 2016 and later.

Restrictions.

Microsoft Hyper-V backup and restore are only accessible through the web interface.

For a complete list of supported guest operating system versions, see Microsoft's Supported Windows guest operating systems for Hyper-V on Windows Server.

Prerequisites for Microsoft Hyper-V Agentless Backup​

You can use the Catalogic DPX Agentless Backup with the following Microsoft Hyper-V environments:

  • Microsoft Hyper-V for Windows Server 2022
  • Microsoft Hyper-V for Windows Server 2016
  • Microsoft Hyper-V for Windows Server 2019

The VMs you want to protect must have the Microsoft Hyper-V virtual machine configuration versions of 8.0 or later. To check the configuration version of a VM, click the VM in the main window of Microsoft Hyper-V Management Console and see the Configuration Version value in the summary tab.

Or, you can get the configuration versions of all or specific VMs by using Microsoft Hyper-V Module for Microsoft Windows PowerShell or Microsoft PowerShell. In the Microsoft Windows Server system, launch Microsoft Windows PowerShell or Microsoft PowerShell with the administrator privilege. Use the following command:

Hyper-V\Get-VM * | Select-Object Name,Version

The command prompts the output that is structured as shown:

Name             Version
----             -------
sales-vm         7.1
service-vm       8.0
development-vm   9.0

In this example, you have to upgrade the configuration version of sales-vm before DPX protects this VM.
