king on her next batch of mosques this humble production a much needed a lifeline for her community. you're watching the news coming to you from berlin don't forget you can also get the latest news and information in our website just go to you dot com american evanston i'll be back at the top of the hour with another news update for you he joins that. this state of emergency normal. people around the world are documenting these dramatic times. they're keeping a diary. and welcoming us into the hours. they let us get as up

close and personal as the pandemic will allow. diaries starts maintained d.w. . in the heart of climate change. africa's most of. what's in store for the claim. for their future. costs for the major cities. inside. the turret. 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. ensure the data we store. be available

to future generations. in the past people recorded important 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 digital memory loss. when it comes to computers things quickly become outdated. collectors like they 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 hard and software the team has often succeeded in restoring data from own 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 so 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 is thought to contain information about a special stamp issued by the swiss postal service in 1996 a lot of those off i hope the drive still works and i need a floppy disk to be intact and it's the i'm optimistic that. plato is

a computer scientist and has been with the museum for almost a decade he's an expert on all salit 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. long is still best film roles for example will still have the photos on them unless they have been improperly stored that video uses magnetic tape which the great slowly and the electronic storage media we use now won't even last 50 years through

the go over there are a. day to 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 in temperature fluctuations and although hard drives and u.s.b. sticks can store large amounts of data they often d. great 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 over to 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 in earth time and his face. says 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 on 2 strands of synthesize do. n.a. this is how it works d.n.a. molecules consist of 4 chemical bases a thought any seed sayto seen finding and g. guanine binary computer code is assigned to these bases respectively then an artificial d.n.a. strand is generated from which this code you 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. and 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 on physicality or to help out industry that's why the tech industry is looking to the world of biology and chemistry to see which other data storage techniques exist. and there you have d.n.a. . off in the. distance of a living lock 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 under an electron microscope each segment can store about 10 killer bytes of data about the equivalent of 2

pages of text. that sense 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. so this really is tiny. if we. amounts we're looking at an entire book of the bill that. on father and we've got the equivalent of an entire shelf of books. 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 also protect it from outside influences and attacks it in the norwegians has created

a special day to conquer the arctic world on kind on spitsbergen island if they plan to store vital data saved on film. we're in the town of drum and noways capital also it's here that are in a bit strongs company is based on the team is 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 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 using the c. so you might you know how the years in us being 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 calls iraq the month 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 cause. they're essentially what happens when you turn binary computer code into 2 dimensional black and white caps. 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 block strong and his team believe this is how we'll be storing data in future. they say under ideal conditions film keeps for over 500 years. and that it superior to alec 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 film from an analog information carrier to a digital information carrier and they 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 retrieve it and just 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'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 school found here libyan strong team has joined forces with a norwegian construction company together they run a digital data bunker so to speak you know we can occupy like you know is a demilitarized zone there full consideration politically listening but just over 2500 people going. to go that there are many defunct coal mines around the main town of longyearbyen and in 2017 the arctic well down kind was opened in one of them since then right. presented is from many different countries institutions and companies have traveled here to secure the 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 open. so this is for us a pull for the concept that it is there that can be kept here as well but for. many many here it's already a firearm. of course the long term threat preservation is reform of the within that the that you can see it included 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 the cloak plan is to create a kind of spot compost humanities collective knowledge some 150 meters from the sky to the dental here protected by the palm of frost will hopefully be safe considering the world's gram data storage needs will soon need for the long term solutions.
