# System Requirements: Live Recovery for Hyper-V

Before performing a live recovery for a Hyper-V VM, verify that your environment meets the system requirements for live recovery.

- You must install the MediaAgent package on the Hyper-V host virtual machine.

- You can use Live Recovery in the following environments:

  - Hyper-V Host versions:

    - Hyper-V Server 2016

    - Hyper-V Server 2019

    - Hyper-V Server 2022

      - Hyper-V Server 2025

  - Hyper-V VM Configuration versions:

    - 5.0 and more recent versions

- You can use Live Recovery with virtual machines that are configured with VHDX disks.

- The Live Recovery feature uses a 3DFS cache on the MediaAgent that performs the live recovery. For each live recovery job, the 3DFS cache requires at least as much free space as the larger of the following values:

  - 20 GB

  - 15% of the total VM size (the sum of the sizes of all VM disks)

Note

For faster recovery times, host the 3DFS cache on a solid state drive (SSD) using flash memory storage.
