Drupal 8 Database Export Guide

Exporting Database from PHPMyAdmin

To back up or transfer your Drupal 8 database, export it via PHPMyAdmin. This process is crucial for preserving your data before making website changes or migrating to another Drupal installation.

Pre-export Steps

Before exporting, it's recommended to truncate cache tables. This action reduces the database size, which is beneficial for hosting services with file size limits.

Exporting the Database

When exporting, select "add DROP TABLE" to ensure the exported database can overwrite existing tables during the import process. This step is essential for seamless database replacement.

Menu Export Module Alternative

For exporting menus specifically, use the menu_export module. It's suitable for users unfamiliar with Drupal's config export/import system and provides a reliable method for menu transfer.

Backup and Migrate Module Option

If menu_export seems complex, the Backup and Migrate module offers a simpler interface. However, it may alter menu order and hierarchy upon import, so assess your needs before choosing this method.

Frequently Asked Questions

Why should I avoid using PHPMyAdmin to export a Drupal 8 database?

Exporting a Drupal 8 database with PHPMyAdmin can lead to a broken database dump and importing such a dump may result in a CREATE TABLE error due to incompatibilities between different versions of MySQL and PHPMyAdmin, specifically with the name column in the key_value table.

What issues can arise when using PHPMyAdmin to export a Drupal 8 database?

Common issues include a CREATE TABLE error when importing the database, which is not specific to Drupal but related to incompatibilities between different versions of MySQL and PHPMyAdmin. The error is often due to the name column in the key_value table.

What is a recommended workaround for PHPMyAdmin issues with Drupal 8 database export?

A workaround for PHPMyAdmin issues with Drupal 8 is to install PHPMyAdmin version 4.7.3, which is known to be more compatible, or to use mysqldump for exporting the database, as it does not cause the same issues.

Is it a good practice to select 'add DROP TABLE' when exporting a Drupal 8 database with PHPMyAdmin?

While the tutorial suggests selecting 'add DROP TABLE' can be a good idea as it allows overwriting tables on import, it is crucial to keep backups and be very careful when deleting server files and databases to avoid data loss.
