This is such an insightful piece. You might not be ready to hear what it really takes.
You should combine every method available to you, layers of backups, armies of copies, and most of all, practices and sites that encourage a culture of watchfulness and care. You should fight for a society that values the sciences and arts and that which they produce. And then, each day, you should do whatever it takes to keep your something safe, do whatever you can to empower the next generation to do the same, and then entrust that battle to them, to repeat into futurity.
