How to Export a Large MySQL Database

Using the Command Line

For exporting a large MySQL database, the command line with the mysqldump.exe utility is highly effective. This approach ensures that you can handle large datasets efficiently.

Using MySQLDumper

MySQLDumper, a PHP and Perl based tool, is ideal for backing up MySQL databases on shared hosting. It can both dump data into a backup file and restore data from it, making it a versatile solution for large databases.

MySQL Workbench Export Wizard

Access the MySQL Workbench SQL Data Export and Import Wizards from the sidebar or main menu to export your data in MySQL SQL format. Utilize the Data Export tab and Advanced Options to fine-tune the export operation, then click Start Export to initiate.
