Raspberry Pi 4, 4Gb, Buster. I moved my boot disk to a Sandisk Cruzer USB. All works fine, but I’m a realist /worrier so I want to take a backup.
I normally use rpi-clone, but obviously this won’t work. I tried dd but my new disk failed to boot. Reverted to my old USB disk and all’s well.
So, can I or can’t I make a backup copy of my disk?
