How backup automated process to my WordPress Sites using code? - wordpress

Question

I have used the code below on the c-panel WordPress repository and created a backup folder in the public HTML folder. But not working on I need to know code issue and where I should customize to get my site automatedly by using code.
`function create_backup() {
// Get the site's URL and name
$site_url = get_site_url();
$site_name = get_bloginfo('name');
// Create a filename for the backup using the site's URL and current date
$filename = $site_name . '-' . $site_url . '-' . date('Y-m-d') . '.zip';
// Create a ZIP archive of the site's files
$zip = new ZipArchive;
$zip->open($filename, ZipArchive::CREATE);
$zip->addGlob(ABSPATH . '/*');
$zip->close();
// Send the ZIP archive to a remote location
// Replace "example.com" with the URL of your remote location
$response = wp_remote_post('http://example.com/backups/', array(
'method' => 'POST',
'timeout' => 45,
'redirection' => 5,
'httpversion' => '1.0',
'blocking' => true,
'headers' => array(
'Content-Type' => 'application/zip'
),
'body' => file_get_contents($filename),
));
}`
Use the wp_schedule_event() or wp_schedule_single_event() function to schedule the custom function to run at a specific time or interval.
And use this Bloew of this code in functions.php
`if ( ! wp_next_scheduled( 'create_backup_event' ) ) {
wp_schedule_event( time(), 'daily', 'create_backup_event' );
}
add_action( 'create_backup_event', 'create_backup' );`
Please notify me where I need to add my domain name and customization needs!
