Access "File formats that stand the test of time"

Published: 19 Oct 2012

Storage professionals are beginning to grapple with long-term data archival. At the same time, archivists and records management professionals have poked their noses out of their musty books and are examining the problem of digital document preservation.

    • File Systems: The state of the art by Brad O'Neill

      Generally overlooked, file systems are assuming a prominent place at the heart of new technologies that address some of the most vexing storage problems, such as scaling and performance. New file-system approaches provide the underpinnings for technologies such as clustering, global namespaces and wide-area computing.

    • Quality Awards: What are the best midrange arrays?

      Midrange array users are a generally satisfied group, according to the latest Diogenes Labs-Storage magazine Quality Awards survey. While all midrange array vendors fared quite well in this third installment of our awards program, the vendor that snared top honors might surprise some people.

    • Secure your backups

      The headlines tell the story: Lost tapes can jeopardize the confidentiality of personal information and cause public-relations woes for those companies charged with safeguarding that data.
