📋 What You'll Learn

Create a plugin file with the correct header

Define a backup schedule interval

Use WordPress hooks to schedule the backup event

Write a function that performs the backup process

💡 Why This Matters

🌍 Real World

Automated backups protect your WordPress site from data loss due to errors, hacks, or server failures by regularly saving copies of your site.

💼 Career

Knowing how to schedule tasks and create plugins in WordPress is essential for developers and site administrators to maintain site health and security.

1

Create the Plugin File with Header

Create a PHP file named auto-backup.php and add the WordPress plugin header with Plugin Name: Auto Backup and Description: Automatically backs up the site.

Wordpress

<?php
// Your code here

Need a hint?

The plugin header must start with /** and include Plugin Name and Description.

2

Define a Backup Schedule Interval

Add a function called auto_backup_schedule() that uses add_filter to add a custom schedule interval named every_five_minutes with an interval of 300 seconds and a display name of Every Five Minutes.

Wordpress

<?php
/**
 * Plugin Name: Auto Backup
 * Description: Automatically backs up the site
 */

// Your code here

Need a hint?

Use the cron_schedules filter to add a new schedule interval.

3

Schedule the Backup Event

Write a function called auto_backup_activate() that schedules a recurring event named auto_backup_event using wp_schedule_event with the interval every_five_minutes. Hook this function to register_activation_hook for the current plugin file.

Wordpress

 300,
        'display' => __('Every Five Minutes')
    );
    return $schedules;
}
add_filter('cron_schedules', 'auto_backup_schedule');

// Your code here

Need a hint?

Use wp_schedule_event to schedule the event only if it is not already scheduled.

4

Create the Backup Function and Hook It

Define a function called auto_backup_function() that will run when auto_backup_event fires. Inside, add a comment // Backup logic here. Hook this function to the auto_backup_event action.

Wordpress

 300,
        'display' => __('Every Five Minutes')
    );
    return $schedules;
}
add_filter('cron_schedules', 'auto_backup_schedule');

function auto_backup_activate() {
    if (!wp_next_scheduled('auto_backup_event')) {
        wp_schedule_event(time(), 'every_five_minutes', 'auto_backup_event');
    }
}
register_activation_hook(__FILE__, 'auto_backup_activate');

// Your code here

Need a hint?

Hook your backup function to the scheduled event to run automatically.
