[Wired] How to properly archive your files

Will you be able to open today’s Word docs in 20 years? Probably not, unless you take some necessary steps to give those digital files an extra-long shelf life.

excerpt:

THE ORIGINAL PROPOSAL for the World Wide Web, written by Tim Berners-Lee in 1989, is an important piece of internet history. It also can’t be opened on modern computers.

John Graham-Cumming, a British software engineer and writer, attempted to open the Word document containing the proposal. Modern versions of Microsoft Word and Apple’s Pages both utterly failed to open the file, as he outlined in a blog post. The open-source word processor LibreOffice worked, albeit with messy formatting. Graham-Cumming ultimately found a PDF exported by CERN in 1998, which was the only way he was able to see the document as it existed in 1989.

It’s worrying that such an important piece of history, in such a common file format, could be almost completely lost to the passage of time and software updates. Anyone with a collection of old digital documents, photos, and videos might be wondering if the same thing will happen to their files, which is the sort of question digital archivists deal with all the time, it turns out. So I reached out to one.

“Twenty years, in the digital realm, is ancient,” says Lance Stuchell, director of digital preservation services at the University of Michigan. His team is frequently tasked with recovering digital files from old computers and storage mediums. “We have a lab that can deal with old media—floppy drives, CDs, older computers. We can get that off of those types of media and move it into our preservation system while ensuring we don’t mess it up while we’re doing it.”

But getting the files off the drive is just the first step: Then you have to open them, and leave them in a state that will be openable for decades to come. It’s a job that’s given Stuchell a reason to think about strategies for keeping documents around as long as possible. I asked him what those of us who aren’t professional archivists should do to ensure our files last decades.
