The longest lived data is replicated data.

Making more copies, with some geographic distribution, is more important than the durability of any particular technology. This applies to everything from SSDs, HDDs, CDs, to paper, to DNA.

If you want your data to last, replicate it all the time.

Wouldn’t that exacerbate bit rot?

  • More chances of bit rot but many more chances of spotting it early and correcting, assuming copies are periodically checked against eachother and errors are corrected
