Unless S/D is intuitive about it like it was the other day when it gave me a choice to push a button to change the format to ..... Can't remember the initials. Anyway, I copied and pasted your directions for future use. I ordered the SD card last night. Now I need to purchase S/D for I can have automatic scheduling for backup.
SD cards, and Thumb drives invaribly come from the factory with a Master Boot Record partition scheme and formatted MS-DOS (FAT 16). However, Disk Utility can easily erase the existing partition scheme and reformat them HFS+ or APFS with A GUID partitioning scheme. Assuming Super Duper uses Apple's cloning utility (the only way to create a bootable clone of the later versions of macOS), erasure and reformating is an inescapable result of the cloning process and cannot be prevented.
