Try this one...it has been tested...if you are going to use mysqli then it will works fine...you may put your code in your controller or model but i suggest to keep this one in your_model & call this function from your_controller...

       $this->load->dbutil();   
       $backup =& $this->dbutil->backup();  
       $this->load->helper('file');
       write_file('your_file_path/your_DB.zip', $backup); 
}
