Money + redundancy

Copies in multiple physical locations. Copies on paper if it's text. Digital copies on tapes and archive quality DVDs. Storage in low UV, low moisture, low everything fireproofed faraday cages.

Store some complete hardware along with some copies for helping to access the data, along with instructions.

Then assume all of that will fail and take a load of money and put it in a trust so it can be accessed at intervals to your descendents upon instructions in your will where an executor (who is also paid well) can verify that they've done the work to copy your data to the new types of media of the day. Include detailed instructions so that the monetary rewards based off a 1% skim off the growth of the invested funds to increase the chance of the investments lasting through generations. Ensure that the executor can pass being an executor on to future generations through additional financial rewards.

Or just don't worry about it. If it's sentimental data have it live on through stories and good memories :)

A layman question:

If Faraday cage holes are smaller than the gamma ray wavelength, does it protect against gamma rays? Or is a thick lead wall needed for M-Disc protection? Is it even possible to construct such small cage holes?

gamma rays = electromagnetic waves

Preserving an M-Disc against a nuclear blast seems futile, as the high temperatures can turn even stone into dust. Is there even a practical way to engineer survival in a nuclear blast? (Any physicists? Engineers?)

Here's a guide on making a Faraday cage, but can it also protect against gamma rays?

>does it protect against gamma rays

Probably not. Might need to throw in some lead, concrete and water barriers.

I wrote my answer as pretty tongue in cheek. It gets to a stage where certain threats being solved for would wipe out humanity anyway, which is why my last suggestion is summarising the lessons of your data into stories and parables to be passed on from generation to generation :)
