Abstract

We as people use computers to store important information because, unlike keeping knowledge in analog(ue) machines, digital computers make exact copies of our files when told to do so.

But do they really? How do we even know if they do?

In this research work, we as scientists examine how computers store information in data structures called file-systems; and by such exploring, we shine a sobering light on important questions (all-too-often ignored by professional software engineers) about how fragile most people’s files really are.

More importantly, we bring a message of hope for both now and the future: (1) Computer Science already provides the mathematical means to make our data safe, and (2) we can start developing new tools, and eventually a new approach to file-system design, which will make everyone’s information both safe and much easier to manage.
