Here are the steps to use to export all your mySQL databases using phpMyAdmin. (Dec 2015) As phpMyAdmin evolves new features are added.
- Open phpMyAdmin and select the Databases tab. Check that all your databases should are listed there.
- Select the Export tab, and then select the Custom tab. You do not want to use the default settings
- All the databases will be selected. Unselect any you do not want to backup. The system files are not included, and you do not need them.
- Under the "Output" option, select "Export databases as separate files". This will automatically change the download file to ZIP with the individual database files in it.
- Move down the the "Object creation options"
- Select "Add DROP TABLE / VIEW / PROCEDURE / FUNCTION / EVENT / TRIGGER statement"
- Unselect the "AUTO_INCREMENT value". Depending on the structure of your databases, you might have to select this. If you are not sure, just keep it selected.
- Click on "Go". The ZIP file will download and you can save that in a safe place.
