For some reason I have had a time finding succinct information on creating a simple full (and by full I mean a file you can use to bare metal recover a database) backup with MariaDB.
1. Make a ~/.my.conf file:
[mysqldump] user=<your_database> password=<your_password>
2. Run this:
mysqldump --add-drop-table -h server_ip database_name | pv | gzip -9 > /tmp/backup.sql.tar.gz
3. Copy your newly created backup file to a secondary storage point.
