Airplanes do not receive OtA updates, nor does every system have a backup. Airplane software is developed to a very high safety standards, which mostly, but not always works. But this is not applicable here. A key part of airplane safety is constant monitoring and maintenance. If a component needs a software update, some technician will manually perform the update and do the required tests. This simply can not work in automotive.
The concept is the same, though.

Every flight critical component and system on an airliner has an independent backup.
