Zálohujte databázi MySQL pomocí CodeIgniter

Zkuste toto. Pokud chcete, můžete změnit formát zip na gz :)

$this->load->dbutil();

$prefs = array(     
    'format'      => 'zip',             
    'filename'    => 'my_db_backup.sql'
    );


$backup =& $this->dbutil->backup($prefs); 

$db_name = 'backup-on-'. date("Y-m-d-H-i-s") .'.zip';
$save = 'pathtobkfolder/'.$db_name;

$this->load->helper('file');
write_file($save, $backup); 


$this->load->helper('download');
force_download($db_name, $backup);
