10. Резервирование данных с машин с Windows на машину с Linux

Adam Neat ( adamneat@ipax.com.au) предоставил следующий скрипт, который выполняет резервирование данных с машин с Windows machines на машину с Linux, используя утилиту smbclient. Adam сказал, что он использует этот скрипт для резервирования данных с машин с Windows 3.x и NT на диск DAT SCSI под Linux.

Adam не гордится стилем программирования, используемым в этом примере, но это работает. Как я хочу сказать: "Если это работает и это сделано тупо, то это не тупо".

Другой скрипт для сохранения данных с Windows, предоставлен Dan Tager ( dtager@marsala.com) и приводится ниже. Скрипт присланный Dan также может сохранять данные с машин с Unix через rsh, хотя он может легко быть изменен для использования ssh.

В этом скрипте строка 'agnea1' является именем пользователя на машине с Linux, на которую производится резервирование данных.
