Some of us are struggling just to maintain our ever-growing archive of photographs and video footage.

But what if you could store half a petabyte, indefinitely?

Well, technically, it’s 13.8 billion years, but for all intents and purposes, that’s pretty much indefinitely.

Valuable personal images might be gone forever (of course, that’s also a good argument for printing your photos), or perhaps you shoot for a living, and keep a permanent archive of all your work.

It’s a lot of hard work to maintain reliable digital backups and to keep shifting all your data from one storage medium to the next generation every few years – especially when some hard drives might not be as reliable as we were led to believe, and cloud services have the potential to accidentally delete data at will.

Scientists at the University of Southampton seem to have found a potential answer for the issue of long term storage, in the form of small glass discs.
