How to fully copy linux instance to another machine

I have a remote google cloud instance which runs Debian GNU/Linux 11 (bullseye), and I would like to create not nessesarily a copy of it, but rather I would like to copy everything that is installed or is stored on it to my local machine. It runs the same version of the operation system and is completely stock. One of the more important aspects of this transfer for me would be Python (which was installed manually) and it's libraries. Is there a way to do this?
