Where would be the best location to store files that need to be updated in a PHP shop on a DVD?

Files that need to be updated in a PHP shop can be stored on a DVD, but it is important to have a backup location as well in case the DVD becomes damaged or inaccessible. One solution could be to store the files on the server and periodically update the DVD with the latest versions. This way, the files are easily accessible for updates while also being securely stored on the DVD.

// Code snippet to store files on a server and periodically update the DVD

$serverFilePath = '/path/to/server/files'; // Specify the path to store files on the server
$dvdDriveLetter = 'D'; // Specify the DVD drive letter

// Copy files from server to DVD
exec("xcopy $serverFilePath $dvdDriveLetter: /E /Y");
