Lesson 3: Updates and Backups

Goal

By the end of this lesson, you will understand why updates and backups are essential and how to perform them safely in the correct order.

Step 1: Why updates matter

Updates keep your website secure, stable, and compatible with new versions of WordPress. Outdated plugins or themes are one of the most common causes of security and performance issues.

Step 2: The correct update order

Always follow this order to reduce risk:

• Plugins
• Theme
• WordPress core

Updating in this sequence helps prevent conflicts and errors.

Step 3: Backups before changes

Before updating anything:

• Ensure a recent backup exists
• Confirm it includes both files and database
• Verify where the backup is stored

Backups allow you to restore the site if something goes wrong.

Common mistakes to avoid

• Updating without a backup
• Updating everything at once
• Ignoring failed updates or warnings

Lesson takeaway

Safe updates and reliable backups are key practices for maintaining a stable production website.
