Are there best practices for managing backup files on a web server to prevent excessive disk space usage?

To prevent excessive disk space usage from backup files on a web server, it's important to regularly clean up old backups and implement a retention policy. This can involve deleting backups older than a certain number of days or keeping only a certain number of backups at a time. By regularly managing backup files, you can ensure that your disk space is used efficiently and avoid running out of storage. 

// Define the directory where backup files are stored
$backupDirectory = '/path/to/backup/directory/';

// Define the retention policy (e.g. keep only the last 7 backups)
$backups = glob($backupDirectory . '*.zip');
rsort($backups);
$backupsToDelete = array_slice($backups, 7);

// Delete old backup files
foreach ($backupsToDelete as $backup) {
    unlink($backup);
}
