My father told me he wanted to make USB flash drives of all the scanned and digitized family photos and other assorted letters and mementos. He planned to distribute them to all family members hoping that at least one set would survive. When I explained that they ought to be recipes to new media every N number of years or risk deteriorating or becoming unreadable (like a floppy disk when you have no floppy drive), he was genuinely shocked. He lost interest in the project that he’d thought was so bullet proof.
M-DISC, at a guess. The media would last long enough at least for grandkids, who will have bigger things to worry about.
Don’t forget, you also need drives that work that long and connect to computers or some other device to utilize the bits, and the bus they use must be available and working, and the disk format they’re written in must be readable, and the images themselves encoded with an algorithm that we still have access to, etc. it’s not just the media.
I think it’s possible, thanks to the retro enthusiasts, we still have access to some things from the 70s and 80s, but they’re getting fewer and fewer, especially in a working state. That’s only 50yrs ago. What happens when you want to go 100? Or 500? A few thousand? We are familiar with journals from the Civil War, and have found items and notes from Egypt, Roman, and Ancient Greek civilizations, how can we preserve what happened in the currently information rich time we live in, for future generations? Especially as much of it migrates online to blog posts and social networks and news sites that eventually shut down due to corporate issues or shifting internet traffic?
Upload it to the cloud and make it someone else’s problem to deal with keeping up with the physical medium changes. Then your descendants only have to worry about figuring out how to deal with an outdated file format they can no longer open… and even when they can finally open it, it’d be super low quality… just like how we have to squint really hard at videos from VCDs now days.
There have been plenty of cloud services that have shut down and taken their data offline. And plenty of current ones deleted data after users have gone inactive. Or require constant payments to keep accounts active. Cloud, as it exits now, is not the answer to the archival question.
You’ll be very hard pressed to find anything else that’d out last the day when all three of AWS, Azure and GCP shutdown and take their data offline.
I get it though, Lemmy doesn’t want to admit these services exist other than to dunk on them in the most anti-corporate fashion… so continue to pretend such is the case!
They take your data down pretty quick when you die and stop paying for it. And as much as we all want to think AWS and GCP and Azure are sticking around forever there’s no reason at this time to believe they will be around in 100+ years.
If anyone is responsible to keep things around for 100+ years, they’d have a job to do… and even then, cloud providers will still make their life significantly easier than juggling a bunch of storage mediums that goes in and out of storage medium fashion.
