This is a bash-script to backup your databases with the most common standard tools.
Important: This Script is developed with debian GNU/Linux so it should work on debian and the most derived distributions.
For the backup of your databases you need a propper client to connect to your databaseserver.
This script aims to backup many different databasetypes eg. postgres, mariadb or mongodb in one single program. So if you have to backup postgres you have to install the psql-client package. If you want to backup MariaDB databases install the mariadb-client package.
