# Database backup ends with a "DV0249 - Unable to read backup data" error

## Issue

> The database backup task ends with the **"DV0249 – Unable to read backup data"** error message.

***

## **Resolution**

Check and resolve any connection stability issues. If the problem persists, you can increase the number of retry attempts in the **Xopero ONE** application—to do this, simply edit the `MaxRetriesCount` parameter in **config.json** file, changing its default value from **2** to a higher one, such as **20**.

{% hint style="danger" %}
To modify the **config.json** file, **you must stop the Xopero ONE agent service**. After making the necessary changes, restart the service and, if needed, refresh the updates in the **Management Service** panel.
{% endhint %}

{% hint style="info" %}
You can edit `config.json` with a simple text editor (i.e., **Notepad++**).
{% endhint %}

The `config.json` file, by default, is located in the following locations:

1. For **Windows**: `C:\Program Files\Xopero ONE Backup&Recovery Agent`
2. For **Linux**: `/opt/XoperoONEBackupAgent/`
