+### Backup all databases & files
+
+**Based on the:** https://lohvynenko.com/ru/blog/a-way-to-get-daily-postgresql-backups-from-docker-swarm.html
+
+* В файле `backups.list` указываются папки, для которых нужно сделать резервные копии.
+* Скрипт автоматически находит все базы данных в postgres db и для каждой делает резервную копию в `.sql` формате.
+* Через заданный в файле `cleaner.sh` в переменной `$EXPIRE_DAYS` срок, устаревшие резервные копии будут удаляться.
+* Для запуска полного процесса нужно запустить скрипт `all.sh` с `root` правами.
+* Это тестовая версия скрипта, здесь могут быть недоработки.
+* Кроме того, необходимо проверить переменные, пути к директориям, которые указаны непосредственно в скриптах.
+
+* В скрипте `remote-backup.sh` приведен пример для удаленной синхронизации папки `backups` с другим сервером. 
+* Скрипт должен быть запущен на другом сервере, нужно правильно указать настройки адреса сервера, пути, и кроме того, на сервере должен быть установлен ключ SSH для доступа.
