As a DBA, you must schedule the crontab script to take the backup of MySQL databases. It is important to configure backup of your MySQL databases either running on Linux or Windows so that you can recover your database in case of any problems occur. MYSQLDUMP is the command using which you can take the backup of mysql databases.
You must check the backup and initiate the fresh backup as a safeguard before upgrading a MySQL database so that you can revert in case of any failure.
Shell Script to Configure Backup of MySQL Database
