information on stone. and preserve their collective knowledge for hundreds of thousands of years. today we're living in a digital age we can store more and more data on smaller and smaller storage units but these are not built to last and we're facing the risk of memory loss. when it comes to computers things quickly become outdated. collectors like phoenix couldn't make a point of holding on to obsolete technology thanks to people like him we can still access information saved on older data carriers. for one thing you need the storage medium to be intact. then you need the appropriate software to retrieve the data and lastly you need an operating system that is

compatible with that software switzerland's computer museum showcases obsolete hard and software the team has often succeeded in restoring data from old storage media . there's usually a workaround for accessing the data but it can be tricky sometimes we need to build an interface converter so we can link the old system to a u.s.b. port we usually get it to work the key criterion is that the old hardware is in good condition. greater bush is the museum's go to guy for retrieving data from old storage mediums his current mission to access data stored on this from the disk it's thought to contain information about a special stamp issued by the swiss postal service in 1996. does off i hope the drive still works and i need the floppy disk to be intact. but i'm optimistic though that. plato is a computer scientist and has been with the museum for almost

a decade he's an expert on data carriers. i hope we can speed this up otherwise we'll have to restart the system now we should be able to reject it. the museum has a vast collection of computer hardened software from different periods in time which means writer can usually find whatever obscure device he needs to retrieve data from old storage media nothing is happening no wait now it is. analog is still the best film roles for example will still have the photos on them unless they have been improperly stored that we video uses magnetic tape which the great slowly and the electronic storage media we use now won't even last 50 years the 3 go over there are. so old

a data gary's can store less but they're often more durable magnetic storage media like floppy disks last only 20 to 30 years optical storage media like cd roms are highly susceptible to scratching and temperature fluctuations and although hard drives and u.s.b. sticks can store large amounts of data they often degrade within just a few short years studies show that our global data storage needs will grow to 175 trillion gigabytes by 2025 to process and store data we need new innovative archiving solutions research is a xerox and a hard looking user one day to carry others been around for millions of years d.n.a. . d.n.a. has 2 advantages it has extremely long jetty so it will last for up to 1000 years i think and it has an extremely high storage density so we can say vast amounts of

data tiny specks. of. classes a chemistry professor at syracuse. together with his colleagues he's developed a method that lets them record digital information like an m p 3 file onto strands of synthesize d.n.a. this is how it works d.n.a. molecules consist of 4 chemical bases. c sayto seen fine and g. kwame binary computer code is assigned to these bases respectively then an artificial d.n.a. strand is generated from which this code is safely stored to be retrieved at a later time. so far this method remains very complicated and expensive but id companies like microsoft have started investing in this field and tech start ups are also looking into d.n.a. as storage media for good reason. you know used to computers having ever greater

storage capacities in processing speed nice light i think that's the physicality at the same time we know that the physical properties on which our computer technology is based have limits or physicality whatever shout industry that's why the tech industry is looking to the world of biology and chemistry to see which other data storage techniques exist there. and there you have d.n.a. . off in the. one reason why d.n.a. makes for a good long term data carrier is that humanity will likely always have an interest in analyzing its own genetic material so it is probable that we will retain the technology to retrieve data from d.n.a. in years to come d.n.a. sequencing capsulated in glasgow supposed to keep for up to a 1000 years there so tiny that they're only visible on to an electron microscope each segment can store about 10 killer bytes of data the equivalent of 2 pages of text. since i think you can see we've got 20 to 30 pages of text.

but we're looking at this in. $200000.00 times magnification of. this really is tiny. if we zoom out we're looking at an entire book of the bit. on the out further and we've got the equivalent of an entire shelf of books to be able to call for more. and you see millions of these class elements so if we had one around the size of a dust particle would have an entire library thinking about. this promising data storage method however is still in the early stages of development. how can we preserve data for a very long time and so protected from outside influences and attacks until the norwegians has created

a special day to conquer the arctic world and kind it's better than island they plan to store vital data saved on film. we're in the town of drum and noways capital or it's here that arena be extra companies based on the teams working on how to preserve data for new eternity but in a sense u.s.b. thumb drives for example are not built to last i could be as i lose i welcome to typical today this fits into my computer but we'll do that tomorrow most likely not because even now you find computers without this u.s.b. interface yet because this is the old one i was u.s.b. see so you might in a 100 years u.s.b. it openly know exactly what is so as now it can fit in the computer when it's in the computer i can take those they don't and i convert them to our super high resolution sure calls and write some of the from. the idea is to preserve the data

for many years to come the company technician retrieves it from the u.s.b. stick and then saves it into queue or quick response. they're essentially what happens when you turn binary computer code into 2 dimensional black and white. this q.r. code is then exposed on an analog black and white film which can eventually be developed. this may not seem like a method from the past but are in a black straw and his team believe this is how we'll be storing data in future just they say on the ideal conditions film keeps for over 500 years. and that it's imperial to electronic media. but in times of everything just digital why such an old school technology so the film medium has been carrying all the additional information from the past into the future of the last 140 s.

so what we did we converted the film the photosensitive film from an analog information carrier to additional information carrier and we did it because of the unique longevity properties and the robustness of the media basically this storage medium is the only self-contained storage medium around that means it contains all the information that you as the client and the owner of these they don't need at an arbitrary point in the shooter to be able to recreate it and to see again your information against as you can see the data stored on film with your bat eyes at the beginning of the road there are even instructions for how to access the information even if you what you're basically saying here is the instruction how to retrieve the data this is human readable information and if this explains in detail about the storage medium how the storage medium is constructed how it's supposed to be stored and kept and then how you can get the data back to data retrieval technology and with this explanation i'm going to understand that in 500 years yes

as long as you are able to read english if you don't understand the language which is there you can use a dictionary to get it into your life to get it ok but how could such films be stored for 500 years to find out we traveled further north to screen found here to be a strong team has joined forces with a norwegian construction company together they run a digital data bunker so to speak the norwegian occupiers you know is a demilitarized zone and the folk inside it particularly stable just over 2500 people coldness arctic occupied ago that there are many defunct coal mines around the main town of longyearbyen and in 2017 the arctic well down kind of in one of them since then. representatives from many different countries institutions and companies have traveled here to secure the store their data in the sun to ring in bunker brody are believed to be being the 1st bit of it wired by stabilized so we

think that they are a very important. business for us support for the concept that it is there that can be kept here as well but for. many many here so maybe a firearm. of course the long term credit preservation is reform of the within that the that it can see to it including france attacks in 2 different data centers about there we believe the law in the importance also augured the positive into this seeds of culture here. don is to create a kind of bangkok post humanities collective knowledge some 150 meters below and to suffer speak to the data here protected by the palm of frost will hopefully be safe considering the world's growing data storage needs will soon need for the long term solutions.
