Find the problem but not the patch .
In /var/www/html/admin/modules/backup/bin/restore.php $vars['items'] are empty .
if (isset($vars['restore'], $vars['items'])) {
$items = unserialize(base64_decode($vars['items']));
if (!$items) {
backup_log(_('Nothing to restore!'));
exit();
}
backup_log(_('Intializing Restore...'));
