and we're all in this together and together make it through. a series of about stacey stacey stay safe please stay safe. while subscribe to d.w. books to meet your favorite writer write checks or whatever it is to share where to find beautiful debris books on you tube. a. 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 how can we ensure the data we store

will be available to future generations. in the past people recorded important information on stone parchment 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 all digital. memory loss . when it comes to computers things quickly become outdated. collectors like fakes 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 a 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 heart and software the team has often succeeded in restoring data from own storage media. or work around 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. later bush is the museum's go to guy for retrieving data from old storage media has 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. i hope the drive still works and i need the floppy disk to be intact. but i'm optimistic 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. video uses magnetic tape which the great slowly and the electronic storage media will use now won't even last 50 years to

go over the product. older data carriers 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 serious and a hard look in 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 save vast amounts of

data tiny specks. of. classes a chemistry professor at. 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 a 3rd and c. sayto seen fine and g. guanine binary computer code is assigned to these bases respectively the 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 i.t. 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 my slight effect as the physicality at the same time we know that the physical properties on which our computer technology is based have limits or physicality. out industry also how that's why the tech industry is looking to the world of biology and chemistry to see which other data storage techniques exist. and then you 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 they're only visible on the an electron microscope each segment can store about 10 killer bytes of data about 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 times magnification. so this really is tiny. if we zoom out we're looking at an entire book of the bill that's. on the out further and we've got the equivalent of an entire shelf of books. or 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. 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 also protected from outside influences and the tasks until

norwegians has created a special day to conquer the arctic world and kind on spitsbergen island they plan to store vital data saved on film. we're in the town of drum and noways capital of here that are in a b. at strong's i t company is based on the team is working on how to preserve data eternity but in a says u.s.b. thumb drives for example are not built to last i could be as i lose i welcome the pick of the day this fits into my computer but will 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 you know hundreds of years in u.s.b. it open he knows that it 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 holes are right and. 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. they skew anchor it 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 be extra and his team believe this is how it will be storing data in future. they say under ideal conditions film keeps for over 500 years. and that it's superior to alec tronic media. but in terms 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 film from an analog information carrier to a digital information carrier and we did it because of the unique longevity properties of 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 data needs at an arbitrary point in the shooter to be able to retrieve it and just see again your information against as you can see the data stored on film with your bat at the beginning of the road there are even instructions for how to access the information even if you're 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 the 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 together ok but how can such films be stored for 500 years to find out we traveled further north to screw around here a little bit of strong team has joined forces with a norwegian construction company together they run a digital data bunker so to speak the norwegian archipelago is a demilitarized zone there full considered particularly stable just over $2500.00 people call us 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 didn't want to since then read. presenters from many different countries institutions and companies have traveled here to securely store their data in the sub to ring in bunkers we're brought here to be the 1st bit of it wired by stabilized it's always

been there they are very important. so this is for us support for the concept that it is they've got to be kept here about but for. many many here it's already a firearm deal. of course so the long term threat preservation is reform of the within that the that they can see deep into de france attacks in 2 different data centers about there we believe the law in the importance also all but that was it didn't get this seeds of culture here. plan is to create a kind of bangkok post humanities collective knowledge some 150 meters from love for scientists the dental here protected by the palm of frost will hopefully be safe considering the world's grown data storage nice will soon need to find the long term solutions.

entering the conflict zone with tim sebastian it's not as if sun to suddenly be moving for a long time about a pandemic but the politicians didn't seem to take much notice fair lack of preparation is now becoming clear my guess this week from brussels is the european commission of home affairs johansson why do you believe you'll get it so wrong conflict. next on d w. hot air in northern greece. coal mining is splitting the population. fear for their jobs in the mines and power stations. others are fighting the old dominant energy corporation the uncle they blame for destroying the environment. the curse or blessing extracting coaling

grease the couple in the middle of it. and 30 minutes on d w. w's crime fighters are back at that but not africa's most successful radio drama series continues all of us olds are available online to war so you can share and discuss song w. africa's facebook page and other social media platforms to harm fighters to mean now cut. the commission have been able to act very quickly if you can find common solutions to common problems what's the point of the e.u. member states realize that if they need each other always get the good news over coffee it will come out of this which is from the corporations it's not as if tsongas hadn't been warning for a long time about the poem going to make bangkok the politicians in many european countries didn't seem to take much notice of the scale of the lack of preparation

to be done is not becoming clear my guess is we close off those of the european commission oklahoma.
