The concept is that you have two copies of critical parts of your OS so you can update easily and never fear being stranded.
In practice the super partition is usually only virtual A/B and you really don't have as much protection as you thought.
Got lots of space on a desktop/laptop? Make a full raw backup of your device and you can always return to the exact same state at a future time. Ok, my Go6 is 32 GB which isn't too bad, but if your device is ginormous...
*But never "factory reset" or "wipe" your device or else the encryption keys are erased and your backed-up userdata will be converted instantly to GBs of random noise.
