Need to archive backup_controllers log, too.

Looks like this is new in Moodle 2.6 and up:

lib/cronlib.php:

        // Delete old backup_controllers and logs.
        $loglifetime = get_config('backup', 'loglifetime');
        if (!empty($loglifetime)) {  // Value in days.
            $loglifetime = $timenow - ($loglifetime * 3600 * 24);
            // Delete child records from backup_logs.
            $DB->execute("DELETE FROM {backup_logs}
                           WHERE EXISTS (
                               SELECT 'x'
                                 FROM {backup_controllers} bc
                                WHERE bc.backupid = {backup_logs}.backupid
                                  AND bc.timecreated < ?)", array($loglifetime));
            // Delete records from backup_controllers.
            $DB->execute("DELETE FROM {backup_controllers}
                          WHERE timecreated < ?", array($loglifetime));
            mtrace(" Deleted old backup records");
        }

@ctam - is this still relevant?

[ctam]

I think so. They have moved the code to here.

Taking a second look, we are not using the 'Automated backups' feature on our site, so this is not important to us. But if we were to implement this, it will make this plugin more complete. There were also discussions that we would want to enable 'Automated backups' on our site. So, we may want to revisit this then. I think we can table this for now.

@ctam Thanks for the feedback.
