# Unable to backup a Hyper-V cluster

## Issue

> You are unable to backup your **Hyper-V** cluster.

***

## Resolution

To secure a **Hyper-V** cluster, install a dedicated backup agent on each **Hyper-V** host. After installation, open [**XMS**](#user-content-fn-1)[^1], go to **Virtual Machines** > **Hyper-V** to add the entire cluster to your backup plan using the dedicated checkboxes.
