Это будет интерактивный способ выполнить резервное копирование, где вам необходимо указать имя / адрес IP-адреса удаленного хранилища и адрес папки.
Мы сохраняем отдельный файл, где вам необходимо указать файлы / каталоги, которым требуется резервное копирование.
Мы добавили два скрипта, в которых первый скрипт запрашивает пароль после копирования каждого файла (если вы включили ключи аутентификации ssh, тогда пароль не будет задан), а во втором скрипте пароль будет запрашиваться только один раз.
Мы собираемся сделать резервную копию bckup.txt, dataconfig.txt, docs и oracledb.
# ls -l total 12 -rw-r--r--. 1 root root 0 May 15 10:43 bckrsync.sh -rw-r--r--. 1 root root 0 May 15 10:44 bckup.txt -rw-r--r--. 1 root root 0 May 15 10:46 dataconfig.txt drwxr-xr-x. 2 root root 4096 May 15 10:45 docs drwxr-xr-x. 2 root root 4096 May 15 10:44 oracledb
Следующий файл содержит данные о файлах и каталогах резервного копирования:
# cat /tmp/bckup.txt /tmp/oracledb /tmp/dataconfig.txt /tmp/docs
