I need to store a 1MB file for 20 years, would making thousands of copies on a 4.7gb DVD be enough?

  • paperback

    Paper backup generator suitable for long-term storage.

    • Paperback will do it automatically for you, open source and free. Thier README also has recommendations for long term storage of paper.

  • MultiPar

    Parchive tool

    • More sanely, perhaps, get some M-Disc DVDs (if you can find real ones - apparently they're becoming just normal DVDs) and put one file on each, and then run https://github.com/Yutaka-Sawada/MultiPar on it to create parity files. Then store the file, the parity files, and the software you need (MultiPar) on the disc. To be safe, you probably also need to store the DVD burner you used to make it, as those are getting thin on the ground these days.
