First, thank you for trying.
There’s what I want and there’s what I’m trying to do. 😉
Waving my magic wand, I’d like a bootable backup of my laptop’s internal hard drive. This is what SuperDuper does. I would like it to be straightforward: I issue one command, then I can boot from the external hard disk to which I have backed up. For bonus points, restore is merely backup in the other direction.
That is what I’d like.
I’m cloning a drive with Clonezilla and tomorrow I’ll try to boot to the backup drive. I would like to understand how restore works, but frankly, I’m not optimistic and I’m not currently eager to risk screwing up my laptop’s internal hard disk.

If you do disk to disk clone, you will make an exact copy of the source disk to the destination disk. BEWARE of the booting from usb when the source drive is installed as well! A modern OS uses UUID’s (identifiers) to manage the hard drives. You are effectively creating a drive and partitions with the SAME UUIDS! There are steps to manage this, but understand it could cause you issues. A simple way to manage that is make sure to simply disconnect the internal drive in the bios when you boot from USB. OR Boot normally, and add a virtual machine to the host and run your USB drive inside the host VM.
