@lorimeyers Right, what I did, was wait until one of the big drive manufacturers had a sale and bought a large external back-up drive. 5TB. I have *everything* backed up on that. Every time I save something, I save it again to the files on that, that mirror all the other smaller drives combined.
It's vulnerable because it's next to the actual PC, but in the event of a disaster - if I'm THERE - it can be grabbed and run with. Otherwise it's vulnerability is the same as anything else one has.
