Optical media starts to degrade after about five years. Hard drives fail in five years, ten if you're lucky.
How do I preserve my digital media so that it's not gone in 20-30 years?
All my googling suggests that I'm best off printing off pictures I want to store in the long run and stick them in a cool, dark, dry place.
Old media (fucking paper) is my preferred for a lot of things. Digital for backup. I think most people save too much. Hundreds and thousands of pictures of old girlfriends, vacations you can't remember, blah blah blah. Maybe I'm just not old enough/too much of a loner to appreciate piles of photos and home movies.
For work I have to think about archiving at least a few (potentially a few dozen) TB of data. The sucky thing about cycling drives is that it's a neverending battle, and a recurring expense. I would do tape if i could afford a reader--to do it now, I'd have to get an archiving service to do it for me, and do my archives all in one big go.

It's one strategy. I wouldn't wager my life that whatever cloud service I pick out of a hat will preserve my data for ever and ever, but it could be one hedge against local catastrophe taking out your local storage (flood, housefire, meteor impact).
I mean gmail had to restore a bunch of accounts from a tape backup not too long ago, right?
It's not in any "cloud". Your data is in a data center somewhere. If a meteor hits the data center, you're boned. And if they get bought out by somebody else and the price goes up, well you're just gonna bend over and take it faggot.
any reputable cloud service will use redundancy and backups so your data is safe, but the cost far outweighs the other options except tape and physical storage
you'll get better cost-efficiency by running HDDs in RAID and replacing them when they fail

Pretty sure I have burned discs going on 10+ years old that still work. If you buy quality media and store them properly I thought optical media was fairly reliable.
I don't know how well it compares to what it claims, and they're expensive per GB compared to conventional optical media, but M-Disc is an optical media designed for archival use.

Point is, even if I have a box with ten hard drives in it, and only one fails after ten years, I've still lost 10% of my data. That might be a small tragedy for someone who hoards tons of home movies and crap, but it's a nightmare for a small business.
A friend of mine who archives data for the film industry is fond of saying "If it doesn't exist three times, it doesn't exist".
10 drives with no redundancy is dumb.
Tapes are a dying format. They may last a while, but the hardware is expensive (for consumers) and HDDs are far outstripping tapes in size. For the money, you're better off buying several HDDs, cloning them, then updating/replacing them every few years.
I have some Kodak gold archival discs from 1998 and they still work perfectly.
But then again all my Apple IIe and Commodore 64 disks from the 80s are fully functional.
If you can keep your shit in a climate controlled place, you're fine.
Get Google Drive or any other cloud service. Once a year make a gigantic GPG encrypted backup of your file (use a strong password and hash it or something along those lines). Upload to cloud
Uploading to Google Drive and Microsoft OneDrive is your best bet.
In the past I stored stuff on cd's but they all died by now. Hard drives have been more reliable, but they still got errors and died with lots of data randomly.
1x Hyper CD-ROM (Petabyte Optical Disc) is all you need.

Fuck your SSDs and Blu-Gays
Optical media lasts a lot longer than it says, so long as it's kept in a cool dark place. I recently pulled a CD out of my wardrobe that was from 2003. It had some pictures and sims mods on it.
Those were the days.
Why not just use an optolythic data rod? Durable, secure, nearly impossible to falsify.
Tape also starts to degrade after 20 years even in ideal conditions.
If you really want to preserve things, etch the data into noncorrosive metal discs, but the tech to do that AND read it will be expensive.
For everything else, solid state drives. The worst thing that can happen is that the controller fails and needs replacement.
Almost all of my audio CD's from the early 90's still work. I have a 640MB hard drive that wont die meanwhile I'm having trouble finding new hard drives that last more than 2 years. Your best bet is to have a backup and promptly replace a drive when it dies.
The whole tape preservation thing goes beyond just air tight containers. For long term storage you need very specific temperatures and humidity, and of course no light or magnetic interference, plus some formats can develop problems with coatings, adhesives and lubricants by themselves.
it has it's issues but if you store it in a vaccum bag in a gun safe you'll be good to go
the better question is what will you do when you're 97 and your great grandkids dump "all of grandpa's worthless shit"?
better to think about this now than later
Here is how my shit is done:
Write onto floppies - leave for a couple of years.
Copy onto CD - leave for a 5-10 years.
Copy onto DVD - leave for a 10-15 years.
Copy onto BD - leave for a 15-20 years.
I'm just getting to the BD.
I've not lost a byte. Ever.
Convenient thing is all of my floppy discs fit onto a single CD-R.
All of my CD-Rs fit onto a couple of DVD-Rs.
All of my DVD-Rs will fit on approximately 10 BD.
I can't lose.

all you need is redundancy. the cloud can help you out if you don't want to deal with it yourself. there are plenty of places where you can get storage on, even for free, so if one place i shut down you still have the other places + your locally stored data.
