# Backup task ends with a "DV0270: User-defined script failed" error

In this article, you will learn how to add the MySQL dump utility to the path variable. This is necessary for define arguments for the MySQL database backup script installed on Linux.

## Issue

> Backup task ends with error: **"DV0270: User-defined script failed"**.

***

## Cause

This occurs because the path to **MySQL** dump is missing from the operating system **PATH** variable.

***

## Resolution

Add the **MySQL dump** utility to the system **PATH** (this is required to allow the **MySQL** database backup script installed on **Linux** to properly define its arguments):

1. Run the terminal as root, for example:

2. Execute the following commands:&#x20;

```bash
mv /usr/bin/mysqldump /usr/bin/mysqldump0
echo '#!/bin/bash' > /usr/bin/mysqldump
echo 'export LD_LIBRARY_PATH=' >> /usr/bin/mysqldump
echo '/usr/bin/mysqldump0 $@' >> /usr/bin/mysqldump
chmod a+x /usr/bin/mysqldump
```

3. Assigning the path to the **MySQL** dump utility should resolve issues with backing up **MySQL** databases.
