WordPress Backup and Migration

Learn how to back up a WordPress website, restore website data, migrate a website to another server, and move a local WordPress project to a live hosting environment.

1. What Is a WordPress Backup?

A backup is a separate copy of your website files and database. It helps you recover your website if files are accidentally deleted, an update fails, a website is hacked, or a server develops a problem.

2. Why Are Backups Important?

Regular backups help you:

• Recover from accidental file deletion.
• Restore a website after a failed update.
• Recover from certain malware or security incidents.
• Move a website to a new hosting provider.
• Recover data after a server failure.
• Test changes before deploying them to a live website.

3. Types of WordPress Backups

4. Create a Database Backup Using phpMyAdmin

phpMyAdmin is a browser-based tool for managing MySQL and MariaDB databases. Many hosting providers include it in their hosting control panels.

Example backup filename:

wordpress_database_backup.sql

5. Create a File Backup

You can back up WordPress files using your hosting file manager, an SFTP client, or a backup tool supplied by your hosting provider.

Important WordPress paths include:

wp-admin/
wp-includes/
wp-content/
wp-config.php

The wp-content directory normally contains themes, plugins, and uploaded media. The wp-config.php file contains database connection details and other configuration. Protect it carefully.

6. Use a Backup Plugin

WordPress backup plugins can simplify scheduled backups and restoration. Features differ between plugins and their free or paid versions.

To install a backup plugin:

1. Open Plugins > Add New Plugin.
2. Search for a reputable WordPress backup plugin.
3. Review its documentation, compatibility, and storage requirements.
4. Click Install Now.
5. Click Activate.
6. Configure the backup schedule and storage location.
7. Create a backup and verify that it completed successfully.

7. What Is WordPress Migration?

WordPress migration means moving a WordPress website from one location or environment to another.

8. Migrate WordPress Manually

A manual migration requires transferring the website files and database, configuring the destination environment, and checking the website after the move.

9. Configure wp-config.php

The wp-config.php file connects WordPress to the database. During migration, database names, usernames, passwords, or host details may change.

Example configuration structure:

define('DB_NAME', 'new_database_name');
define('DB_USER', 'new_database_user');
define('DB_PASSWORD', 'your_database_password');
define('DB_HOST', 'localhost');

10. Import a Database Using phpMyAdmin

To import a database backup:

1. Open phpMyAdmin on the destination server.
2. Select the destination database.
3. Click the Import tab.
4. Select your SQL backup file.
5. Choose the appropriate import settings and format.
6. Start the import.
7. Check for errors and confirm that the expected tables exist.

For a large database, use an import method supported by your hosting provider if phpMyAdmin's upload or execution limits prevent the import.

11. Update Website URLs After Migration

If a website moves to a different domain, its database may still contain references to the old domain. These references can affect links, images, menus, and other settings.

Example:

Old URL:
http://localhost/mywebsite

New URL:
https://example.com

Replace these example URLs with the actual source and destination URLs for your website.

12. Migrate WordPress from Localhost to Live Hosting

Developers often create WordPress websites locally before publishing them online.

Follow these general steps:

1. Finish and test the local website.
2. Export the local database.
3. Back up the local WordPress files.
4. Prepare hosting, a database, and a domain.
5. Upload the files and import the database.
6. Update database credentials and URLs as necessary.
7. Configure HTTPS and verify DNS.
8. Test links, images, forms, logins, and important features.
