An what would be the proper way to do it?

For me, this is the proper way of doing updates in a computer: - create a full backup (bootable image) in an external disk - apply the update - if happy, let's move one. if not, recreate the image of step one.

You could argue that you do not need the whole image of the computer, only the image of the system. Well, the system in a computer is from 1Gb to 4Gb.

In an iOS device, the system would be between 500Mb and 1Gb. At least, you need to back that up, and OTA is not feasible right now.
