    I didn’t know DVDs are supposed to last 100 years. That’s definitely not the case with newer storage media, be it BluRay, hard disks or even worse SSDs.

      Modern Blurays should actually last longer than DVDs. Bluray M-Discs supposedly even last 1000 years. 100 years for DVDs is pretty optimistic. 20-50 years is more realistic.

        Apparently there’s some huge drama in data hoarding communities about manufacturers switching between different recording technologies, and how everybody is worried that they aren’t going to last for 5-10-100-1000 years.

          I have 3 physical backups of all my stuff, one a rotating offsite backup. The backup media gets replaced over time.

          I don’t expect media (especially backup media) to last more than 10 years. But it doesn’t matter, as my NVMe backup solution of today looks nothing like my spinning rust backup solution of 20 years ago, despite holding all of that data.

            invest in a tape backup, tape formats like LTO will last LTO tapes are cheap and durable. Write time can be slow but reading is quick enough for what it is

            sure an EMP might corrupt it but if you are that paranoid, you could use a safe for shielding
