I always have an backup online & mobile as I said earlier
, no need to fear for the wipe out or virus attack, as there are only slim chances that both the original and backup files are wiped out.. Also, if you say I'm using more memory then a text document takes memory in few Kb's
Now I would like to add onto it, that suppose you are writing your ideas on a paper and by mistake or due to some natural or artificial cause the written docs are on fire, then you will also loose them
So, I would be in more advantageous position than the paper writers
