Is there a way for me to copy/clone/backup my user on my MBP onto another machine like a Mini? For example, I flip a "switch", my MBP user is copied/synced/whatever to the other machine so that if my MBP goes down or is damaged, I can bring up that user as us the most recent backup. Can I do this on another machine, or on an external drive that can be connected to another machine and recognized as a user of that system? I'm looking to backup and use a user, not an entire system. Thanks in advance.
