Just for the sake of argument, let's say I do something stupid and my zbitx will no longer boot. But I have done a SD card copy to an external usb with new UUID.

How do I boot from the USB so that I can copy the system back to the internal SD card thereby restoring my zbitx and making it bootable again?

If you want a quick answer, copy the uSD card from the working system (you can do it with an SD card reader) and then swap the two cards.

Due to the small size, booting from an external USB increases the portability. As far as I know, this was also the goal of zbitx, to be small and portable.

By the way, if you want to experiment with this external USB boot, you can read the solution on the JJ wiki how it was implemented at sbitx.

The microUSB is probably usb 2, so I think you can't achieve a speed increase with this.

I follow what you are saying.? However the sdcard in the zbitx is? internal. I was hoping that a sdcard in a card reader in the USB port can be booted instead of booting from the internal card.

With sbitx, it is worth booting from an external USB 3 because there is a speed difference.

Here, the RPi4 also boots from the uSD card on the pcb, while the uSD has a speed of 30 MB/s, while the external USB 3 speed (depending on the quality of the stick) reaches a 10x increase.

I recommend replacing the internal uSD card because I think there is not that much gain with the external USB.

I'm looking at? it from a backup restore perspective.
