<Tip>
  For backup and scheduler, we have installed and configured one of the most popular PHPBU solution. We recommend to see [https://phpbu.de/manual/current/en/installation.html#installation.requirements](https://phpbu.de/manual/current/en/installation.html#installation.requirements)

<Info>
  This extension may not works well on shared server, due to PHPBU's SSH command execute ".phar file" with PHP's exec() and shell\_exe().
