Bit Rot Stalks Your Digital Keepsakes

axlrosen writes "The NYTimes has an article about the problems of digital archiving. How many of your digital memories will still be around 50 years from now, considering lost disks, incompatible formats, hard drive crashes, fading CD-Rs, etc.? Unfortunately Peter Briggs' solution won't work for most of us. The only real way to make sure that your grandkids get to see your digital photos is to make real photographic prints from them. (When I bought my Mom a digital camera I installed Picasa for her, and made sure she knows to order real prints of all the pictures she wants to survive through the ages...)"

      Or rather, dispense with the concept of permanent media altogether. I realised a few years ago that the only sane way to protect my data was to have it all online all the time. I store my data on redundant arrays of disks in two geographical locations (my house and my parents' house, synced nightly via rsync). This is IMHO a far better solution than backing up to tape or CD/DVD. LVM makes the process of moving the data to bigger disks trivial. Where it falls down is for really large volumes of data. Places like CERN that generate terabytes of data per day are going to struggle in the not too distant future. Archived data will become a real problem (even more than it is now).

    Alien v Predator script saved by Internet pirates

And I ended up losing the Amstrad disk, which was some weird, unreadable proprietary brand anyway.

    But the main problem is not the "end of life" of media used for storage, is the format in which the information is. In 50 years, will be an application that opens/process that information? One of the advantage of having information in open formats is that in the worst case, you can have all the information to be able to process them. But if you stored your information using an applicaiton with its own propietary/closed format, and the company just decided to not support that format anymore, or just closed, you could have lost your information, even if the media where it is stored still retains it well.
