[Blade Runner] If I had foreknowledge of the Blackout of 2022, how could I go about protecting the data on a single hard drive?

Would it be possible by, say, putting the drive in a lead safe lined with rubber and a Faraday cage? Would that be overkill or would it not be enough?

The easiest way might be to backup the data to optical discs or something similarly resistant. A faraday cage would work if you need to save the hard drive itself or don't have enough forewarning to perform a full backup.
