Добавляем скрипт в System — Scripts , например с именем backup
После чего добавляем в System — Scheduler задание с именем backup и выбираем желаемый интервал выполнения.
Для проверки скрипта, можно его запустить и получить на почту текущие настройки. Очень полезно когда Вы экспериментируете со своим оборудованием.
