You've been tasked with conserving 500gb of data indefinitely...

blockchain

Actually I think storing the data on physical tablets isn't the safest method. What if a natural disaster destroys the tablets? I have a better idea. Do the tablet method and distribute them around the world while constantly broadcasting the data out into space. That way even if humanity died and the entire earth was destroyed the data would still be traveling through space at the speed of light for thousands of years. Sure CATCHING that data would require FTL travel but OP never mentioned we had to be able to get to it.

*Lead lined

Basically you get to set up a cult devoted to maintaining your data.

Reliability of the storage medium isn't your biggest concern, once you get into time periods measured in decades. Your problem is that different media standards and file formats and operating systems and so on come into use and the old ones fade away. Say you have a bunch of eight-inch floppy disks from the 70s, stored in a cool, humidity-controlled environment. The disks are almost certainly still legible. But do you have an eight-inch floppy drive? If you do, do you have a machine that can talk to it? Does it run an operating system that understands the filesystem on those disks? If so, do you have software that can still read whatever format the files are in?

You can't anticipate this ahead of time, either. In the late 70s eight-inch floppies were pretty common, and using them to store things was a sensible choice. Then the IBM PC took over the world, and it had been born with smaller 5.25" drives. Those became common and 8" went extinct rapidly. Then 5.25" died as everyone moved to 3.5", and now you have a hard time finding a machine with ANY floppy drive.

The only way around this is active maintenance. Someone needs to be around to read the data every few years, transfer it to new media and new file formats. There's no way to save things by just writing them once and leaving them alone. Unmaintained data crumbles away to dust and there's nothing you can do about that.

i think i rather go with the metal tablet that has the info physcially engraved into it instead

OP never said it should be easy to get the data back or anythnig just that it does not disapear

Etch the data in fundamental quantum constants

Smarter men than us have done this thought exercise. It's physically impossible to get to actual 100%. And getting to "1 byte decay per lifetime of the universe" is just a matter of redundantly implementing all the known techniques.

These big companies put billions of dollars into solving the easy problem of figuring out how reliable storage mediums and storage techniques as well as the hard problem of figuring how to arrange these infrastructures in a way that they can practically be accessed, maintained, and modified.

What you're asking for is the data equivalent of a perpetual motion machine.

Just jump ship. This ain't no exhentai neckbearded sysadmin baby throwing a tantrum; it's a multi-billion-dollar company. You'll KNOW when they're going out of business.

Create a monastery with an order of monks who must maintain the files integrity.
Have two temples in safe locations well above sea level and far enough apart that natural disasters are unlikely to affect both.

Copy the data to multiple HDDs, 10 for each temple. Have 2 checksums for the data - sha256 and sha512. Carve these checksums onto metal slabs so that they won't get lost or degraded.

Every 5 years the monks must copy the files to new HDDs as part of their ritual and test the integrity after.

I think the biggest problem with constantly transferring the data into new mediums is that it runs the risk of slightly changing the information. Remember, the goal is to make sure the file is 100% the same. Bit for bit. Unless the technology of the past is actually lost an older format won't be unreadable. If scientists 500 years from now found a floppy disc and REALLY wanted to read its contents they could just build an old PC.

>"1 byte decay per lifetime of the universe"

wat? so then the universe die, we only lose 1 byte? i would assume everything is lost then

Here's a cool storage method most people don't know about. NASA had to come up with a light weight and robust method of memory storage for the apollo missions. Their solution? Literal strings of wire HAND WOVEN into configurations of rope to execute code on an electromechanical basis.

Buy 20 different dedicated servers around the world and have them host copies of the data, if one provider is going to go under just swap to another. You could also replicate the same thing with small devboards like pi's just thrown around the place with a copy and an internet connection

inscribed rocks

i'll just put it on my SSD

You CAN get 100%. It's just a question of how long. I could make a computer by hand out of a few logic gates with a couple bytes of memory and it would be able to retain that memory for decades until the logic gates decayed. It's just a question of scaling it up.

How does this work?

We're also going to have to arm these monks. We cant run the risk of a religious purge in the 2700s wiping them out and destroying our 500gb of anime. Allocate 3 billion dollars to outfit the monks with military grade weaponry.

Store it on some HDD's, pack it on a spaceship, and YEET it into interstellar space, where you can just stomp on those brakes, and get that ship to a stop.

Interstellar space is extremely close to absolute zero, practically on it. So no particle will be able to move on its own. And thanks to space actually stretching this spaceship will NEVER find another star to warm it.

looks like it would be easy for one of the string to snap though, why not etch it like some other read only chip?

"You shall have no other gods before Me.
You shall make no idols.
You shall not take the name of the Lord your God in vain.
Keep the Sabbath day holy.
Honor your father and your mother.
You shall not murder.
You shall not commit adultery.
You shall not steal.
You shall not bear false witness against your neighbor.
You shall not covet."

This has 336 characters. If encoded in ASCII it's going to take 2688 bits. You might use more if it was in the original latin and you could probably shrink it using Kanji. Either way, this is much less than the 4000000000000 bits required to store 500gb of anime. God had it easy.

Simply report back, whenever asked, that all the data is ok. Keep spending maintenance money on hookers and blow.

Because this method is much lighter than other methods of data storage at the time. It's also immune to radiation changing bits. Keep in mind the origional Apollo guidance computers only had 4 16 bit registers to work with. Even one bit in that going off would be catastrophic.

Also these are very short strings and made of copper. They aren't going to be swaying around or anything.

10thpbp

some sort of p2p fs (like but NOT ipfs).

It's literally the only way to ensure that it's redundant.

>magnetic core memory

Get zoomer.

i just checked this out in wikipedia, and it says that nobody knows what this means, even the incas have forgotten the code they used. make you think.

maybe storing things in binary code is not enough, if you dont know the interpretation like the mapping from bianry to ascii. or from binary to pixel placement and colors

I posted the wrong image. That is an image of magnetic core tech which was invented in the 40s but I about is Core Rope Memory which functions differently and actually was invented by NASA for the Apollo missions.

>but I about is Core Rope Memory
Typo. Meant to say "but what I was talking about is Core Rope Memory"

What was written on those disks lost all relevance anyway, and it happened in just a couple of decades.

Google throws exhentai-tier tantrums, why amazon can't?

I believe the Scientologists use like titanium plates with the data etched into them or something

Just store them sensibly then.

isn't that googs just trying to save every bit it can?
I'm sure they do even more compression after the fact.

Laminate them like a civilized person

It can be compact.

Also anime from 80s is quite irrelevant, and it's only 30 years old.

Useless. NAND flash loses data over time if not powered on.

No, but the acid in the paper already will.

user would spend more time and resources getting the old valve computer to read and interpret and finding a way to hermetically and vacuum seal the the paper than he would being able to akshully archive it. Let alone finding a warehouse space that will still be there in a decade.

>God had it easy.
But god literally used p2p - get chump to scratch out story, make sure it's passed from person to person (iterated generationally if possible).

"Hire" a couple billion chinks to hand carve the data into gold or something and gently set it on the moon.

We're not providing them with a way back right?

you forgot Florida

Look for the 500GB sequence in PI, with some luck it'll happen to be just beyond the current most distant digit we've calculated. Then exterminate all human life on earth except for one line of human that has been genetically engineered to contain this sequence in a highly conserved part of the DNA, similarily to the known universally conserved ncRNAs. Do the same for all other life forms.

>genetically engineered to contain this sequence

The sequence of numbers that identifies the 500GB string in PI that is.

depends on how indefinite you're talking about, but making 5D optical data storage more of a thing and writing it onto a pair of those quartz discs would do it.
