Hidden script to copy content of USB

Is there a program or a script for Windows (powershell maybe, or cmd) that can detect when a USB drive is plugged in and copy its contents in the hard drive of the PC?

It should be able to act autonomously without asking permission or opening confirmation or status windows.

I need it to create a backup of the drive every time that I connect it to the machine.

This vbscript is used to automatically copy each and every newly inserted USB key or sdcard. For each USB key or every sdcard, it creates a folder of this form "MachineName_VolumeUSB_NumSerie" in the% AppData% folder and it makes a total copy for the first time and then incrementally, ie, it just copy the new files and files changed every 30 seconds.

'Sauvegarde automatique des clés USB et SDCARD dés leurs insertion.
'Ce Programme sert à copier automatiquement chaque clé USB nouvellement insérée ou bien une SDCard.
'Il sert à faire des Sauvegardes incrémentielles de vos clés USB.
'Pour chaque clé USB, il crée un dossier de cette forme "NomMachine_NomVolumeUSB_NumSerie" dans le dossier %AppData% et
'il fait une copie totale pour la première fois, puis incrémentielle , càd ,il copie juste les nouveaux fichiers et les fichiers modifiés.
