You are absolutely right. What I meant is the implication that it can have beyond having copies, like doing legal paperwork to 3 or 4 government services because we need to update our email and credentials (I live in a country that is not tech friendly regarding to any administrative matter and it's a real nightmare sometimes).

And speaking of that, I tried once to create my own email server...so maybe I have to retry that and make a contingency plan, investing in a local server lab and preparing for the worst scenario.
