How burn big iso images from Relax-and-restore?

Dear community

We are struggling to burn a big iso image generated by Relax-and-recover ("Rear"). The Rear image is around 10GB, and using the UNetbootin (Linux) is taking days. If I try to use "Rufus" (Windows), after (more or less) 4 hours, a Windows Explorer process locks the usb, and the burning fails. Burning the usb with the command "dd" didn't work either.

So the question is: how the community burn the iso images generated with Rear?

Thanks in advance.
