# Requirements

## Hyper-V host OS

To back up virtual machines directly from the Hyper-V host, you need to run **Windows Server 2016 or newer**. Integration with older operating systems is <mark style="color:$danger;">**not possible**</mark>.

{% hint style="success" %}
In addition to **Windows Server** editions, **Xopero ONE** supports the **Hyper-V** feature in **Windows 10**.
{% endhint %}

***

## Host types

**Xopero ONE** supports both standalone hosts and hosts connected in clusters. In clustered environments, you must install a dedicated **Hyper-V** agent on each host.

{% hint style="danger" %}
If the hosts are clustered, you cannot add a single host.
{% endhint %}

***

## Account type

When adding a **Hyper-V** cluster, you must use an **administrator account**.
