Ubuntu – Create bootable backup system image


I have successfully installed 20.04 and done lots of customization. In the event of a tragedy I would not like to have to start all over again. Is there a simple way (suitable for us newbies) to create a bootable thumb drive image of the customized system, preferably (but not necessarily) including user files, that I could use to restore the system to its current state?
I am running on a Dell XPS 410 desktop computer.
My apologies if this has been answered previously.
Thank you.
