Cloning a live USB

I am looking for some answers about how to safely make a cloned .iso image, or .img, of a functional Fedora Sugar on a Stick installation I have on a USB. This cloned image is to serve as a backup to be burnt to a USB if a catastrophic failure occurs.

Simply put I was having trouble successfully writing a Fedora image to a USB using my current system, Ubuntu. I had various issues regarding the master boot record. Eventually I had to use a Windows based PC at work which pulled me away from my Linux learning experience.

Preferred answer (longer):
If I use the
dd
command will I still have the potential of having to set up the MBR of a new USB or can I just write the cloned Fedora image, after the fact, to the target device and go?

Ubuntu answer (shorter, software):
Has anyone found an image burner on Ubuntu that functions well at writing Fedora, and optionally BSD images?
dd for me has been patchy, and etcher/disk image burner threw up MBR and miscellaneous errors.

Kind thanks for your time,
be well.
