What are some common pitfalls to avoid when implementing an automatic database backup system in PHP?

One common pitfall to avoid when implementing an automatic database backup system in PHP is not properly securing the backup files. It is important to store the backup files in a secure directory that is not accessible to the public to prevent unauthorized access to sensitive data. 

// Set the directory path for storing database backup files
$backupDirectory = '/path/to/secure/directory/';

// Check if the directory exists, if not create it
if (!file_exists($backupDirectory)) {
    mkdir($backupDirectory, 0777, true);
}

// Backup database and store the backup file in the secure directory
$backupFile = $backupDirectory . 'backup_' . date('Y-m-d_H-i-s') . '.sql';
exec('mysqldump -u username -p password database_name > ' . $backupFile);
```

Another common pitfall is not scheduling regular backups. It is essential to set up a cron job or a scheduled task to automatically run the backup script at regular intervals to ensure that the database is consistently backed up.

```php
// Set up a cron job to run the database backup script daily
// Add the following line to your crontab file
// 0 0 * * * php /path/to/backup_script.php
