Shift special how can we preserve our data for future generations. From photographs to Scientific Research to open source code we store much of what we produce digitally however most digital storage mediums will degrade over time and software for retrieving data is constantly evolving so. The data we store will be available to future generations. In the past people recorded Important Information on stun. And preserve their collective knowledge for hundreds of thousands of years. Today were 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 were facing the risk digital memory loss. When it comes to computers things quickly become outdated. Collectors like phoenix couldnt 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 a storage medium to be attacked. Then you need the appropriate software to retrieve the data and lastly you need an operating system that is compatible with that software switzerlands Computer Museum showcases obsolete hard and software the team has often succeeded in restoring data from own storage media. There is usually a workaround for accessing the data but it can be tricky sometimes we need to build an interface converters 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 museums go to guy for retrieving data from old storage mediums his Current Mission to access data stored on this floppy disk is thought to contain information about a special stamp issued by the Swiss Postal Service in 1996. Does he offer i hope the drive still works and i need the floppy disk to be intact. But im optimistic that. Right oh is a Computer Scientist and has been with the museum for almost a decade hes an expert on obsolete data carriers. I hope we can speed this up otherwise well have to restart the system now we should be able to reject it the museum has a vast collection of computer hard and 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 it. Uses magnetic tape which the great slowly and the electronic storage media we use now wont even last 50 years the. Older data carries can store less but theyre 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 de grange 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 direct its a hard one data carrier thats been around for millions of years d. N. A. D. N. A. Has 2 advantages it has extreme longevity so it will last for up to 1000 years i think and it has an extremely high storage density so we can save vast amounts of data tiny specks. Of. Classes or chemistry professor at zurich together with his colleagues hes 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 a fight any sayto seen finding and gene. Binary computer code is assigned to these bases respectively then an artificial d. N. A. Strand is generated. Which this code is safely stored to be retrieved at a later time. So far this method remains very complicated and expensive but i. T. Companies like microsoft have started investing in this field and tech start ups are also looking into d. N. A. And storage media for good reason that youre used to computers having ever greater storage capacities in processing speed nice light i think thats the physicality at the same time we know that the physical properties on which our Computer Technology is based have limits. Or doesnt shout industry thats why the Tech Industry is looking to the world of biology and chemistry to see which other data storage techniques exist. And then who have d. N. A. Dauphine. 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. Segments and capsulated in glass are supposed to keep for up to a 1000 years there so tiny that theyre only visible under an electron microscope each segment can store about 10 killer bytes of data the equivalent of 2 pages of text. A sense i think you can see weve got 20 to 30 pages of text. But were looking at this in 200000. 00 times magnification. So this really is tiny. If we zoom out were looking at an entire book of the. Further and weve got the equivalent of an entire shelf for books. And more. And you see millions of these glass elements so if we had one around the size of a. Dust particle would have an entire library because. This promising data storage method however is still in the early stages of development. Preserve data for a very long time and also protects it from outside influences and attacks a team of norwegians has created a special days of bunker the arctic world and kind that in iceland they plan to store vital data saved on a phone. Where in the town of drum and noways capital all its here that are in a b. At strongs company is based on the team is working on how to preserve data eternity but in a sense u. S. B. Thumb drives for example are not built to last i could be as i would use are welcome to typical today this fits into my computer but well 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 used to see so you might say you know how the early years in u. S. B. It open he knows that it is so as now it can fit in the computer when its in the computer i can take those they dont and i convert them to our super High Resolution sure calls a right amount of. 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 q. Quick response codes. Theyre essentially what happens when you turn binary computer code into 2 dimensional black and white caps they skew our 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 arena being strong and his team believe this is how it will be storing data in future. They say on the ideal conditions film keeps for over 500 years. And that its superior to eric tronic media. But in times of everything gets digital why such an Old School Technology so the film medium has been carrying all the Additional Information from the past into the future the last 140 s. So what we did we converted the film the photosensitive phone from an analog information carrier to Additional Information carrier and we did it because of the unique long Trilogy Properties and the robustness of the media basically this storage medium is the only selfcontained storage medium around that means it contains all the information that you as the client and the owner of these they dont need at an arbitrary point in the shooter to be able to retrieve it and to see again your information against as you see 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 basically see 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 its supposed to be stored and kept and then how you can get the data back the data Retrieval Technology and with this explanation im going to understand that in 500 years yes as long as you are able to read english if you dont understand the language which is there you can use a dictionary took to get it into your life together ok but how could such films be stored for 500 years to find out we traveled further north to schmidt found here libyan strong team has joined forces with a norwegian Construction Company together they run a digital data bunker so to speak the norwegian occupier like you know is a Demilitarized Zone theyre full considered particularly stable just over 2500 people coolies 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 red. Presented from many Different Countries institutions and companies who have traveled here to secure the store their data in the subterranean bunker near brody are believed to be the 1st bit of it wired by stabilized so we think that there are very important. So this is for us support for the concept that it is there that can be kept here about but for. Many many here its already a firearm. Of course the long term threat preservation is reform of the within that the that it can see into de france facts in 2 different data centers about there we believe the law in the importance also augured that was it didnt get this seeds of culture here click on is to create a kind of backup of humanitys collective knowledge some 150 meters from those scientists the data here protected by the permafrost will hopefully be safe considering the worlds gram data storage niece will soon need for the long term solutions.
