Follow these steps to export the entire MySQL database, or export selected tables of the database, to a file and download it to your computer.

Access your database via PHPMyAdmin: This function can be located within your cPanel Account - PHPMyAdmin

On the phpMyAdmin home page, select the database that you want to export from the left-hand menu.

From the tabs at the top of the page select Export.

To export the entire database, continue with the next step:

To export only specific tables in the database, below Export method select Custom - display all possible options, and in the Tables list select only the tables you want to export. Leave all other options set to their default values.

Click "Go". You'll be prompted to open or save the file.

Click "OK". The database or table from the database is exported as an SQL file.
