Backup issue in script

You receive message: Unsupported feature of the database platform you are using.

You can try with another driver, edit file: application/config/production/database.php

in line:

$db['mysql']['dbdriver'] = 'mysqli';

In this case for example change from mysqli to mysql

Also it’s safer if you backup via cpanel, so just backup there:
