Are there alternative methods or tools that can be used to automate database backups more efficiently than the current PHP script setup?

The current PHP script setup for automating database backups may not be the most efficient method. One alternative approach could be using a dedicated database backup tool or service that offers more robust features and scheduling options. This can help streamline the backup process and ensure data integrity.

// Example of using a dedicated database backup tool like mysqldump
exec('mysqldump -u username -p password database_name > backup.sql');
