Go with whatever works consistently and your can trust. So don't use a piece of shit like evernote, for example. This is where paper-based systems can shine (until you can build your OWN digital system). Can't even count how many times I had a perfect digital system set up only to find one stupid little thing about it I could not change because it was not my code to change.

Ideally we would have a digital system that works with our own unique way of thinking. Until then, paper sucks but it's the best.

Why do you need to keep a backup? A good analog system doesn't need to be inefficient. If you can stumble upon the right setup it should be plenty efficient, unless you can build your own digital system.
