How to store digital files for posterity? (hundreds of years)
I have some family videos and audios and I want to physically save them for posterity so that it lasts for periods like 200 years and more. This allows great-grandchildren and great-great-grandchildren to have access.
From the research I did, I found that the longest-lasting way to physically store digital content is through CD-R gold discs, but it may only last 100 years. From what I researched, the average lifespan of HDs and SSDs is no more than 10 years.
I came to the conclusion that the only way to ensure that the files really pass from generation to generation is to record them on CDs and distribute them to the family, asking them to make copies from time to time.
It’s crazy to think that if there were suddenly a mass extinction of the human species, intelligent beings arriving on Earth in 1000 years would probably not be able to access our digital content. While cave paintings would probably remain in the same place.
What is your opinion?
Digital? No. You want durable, you go physical. Print the photos with real archive-quality processes and materials. Same for video and audio, but on film. Keep a 3-2-1 backup in climate-controlled environments.
If you really really want digital, the media doesn’t matter, because you’ll always have to migrate to current formats. Someone will have to be actively maintaining it.
Yeah, I’d say at least every ten years I’ve replaced all my media. Hard drive failures, tape upgrades, physical media changes, tech just moves so quickly. Even if the media survives 100 years, will we still have the tech to read it?
