# License administration

## Viewing licenses <a href="#viewing_licenses" id="viewing_licenses"></a>

{% hint style="info" %}
Types of licenses you see in **Xopero ONE** console may vary a bit from its business models— licenses used in **Xopero ONE** are assigned to agents that are doing backup (endpoint, server, feature worker, cloud worker, local worker) or to backed-up objects (as a **Microsoft 365** user or a **Git** repository).
{% endhint %}

To see all of your available licenses in **Xopero ONE Management Service** go to **Settings** > **License** > **See details**.

## Refreshing licenses

{% hint style="warning" %}
This section does not apply to services operating in the DMZ.
{% endhint %}

**Xopero ONE Management Service (XMS)** must periodically synchronize with the licensing server to verify the validity of your subscription and to adjust to any changes, such as added storage capacity or new licenses.

**How it works:**

* **Automatic Refresh** — by default, **XMS** automatically refreshes your licenses once every **24 hours**.
* **Offline grace period** — to ensure continuity in on-premises environments, **Xopero ONE** allows the system to continue all backup and restore operations for up to 3 days without a successful license verification.

{% hint style="danger" %}
If the verification fails and your license package is not verified within three days, the **Management Service** may stop working.
{% endhint %}

You can manually trigger a refresh if you have recently modified your license (e.g., upgraded your plan) and want the changes to take effect immediately without waiting for the automatic daily refresh cycle.

To refresh your licenses go to **Settings** > **License** and hit the **Refresh** button under your available license package.

## On-premises licenses

The on-premises deployment model requires your [**XMS**](#user-content-fn-1)[^1] to connect with the **Xopero ONE** license server <mark style="color:red;">**once every three days**</mark>.

This process is performed automatically. If the device with **Xopero ONE** installed has no internet connectivity, you can configure the specified rules to allow the device to connect to the component listed in the below table.

| Component      | Port        | IP address      |
| -------------- | ----------- | --------------- |
| one.xopero.com | 443 (HTTPS) | 213.222.221.126 |
