Find a firmware update for your box and download it to a safe place. That way you'll be able to reinstall it in the future in case it's needed.
Thanks for the reply, and thanks again for your work on the build for this box!
My Google search turned up this link for the x96 firmware: X96 (S905x) Android TV Box - Updating the Firmware and Costom Roms: 12 Steps. Does anyone have experience with the x96 box Android firmware? (As you might expect the box itself came with absolutely zero documentation.) I guess if there is nothing to be backed up from the box itself, I really don't need to concern myself with finding a recovery firmware unless I want to restore it some day.
