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. By starting at the application layer rather than at the physical device layer, they seem to be making progress. This fall, the International Organization for Standardization (ISO) approved PDF/A, a version of Adobe Systems Inc.'s Portable Document Format (PDF) file format suitable for long-term archive. As a subset of PDF version 1.6, the goal is to make documents stored in the PDF/A format recoverable and viewable for a much longer time than if they were saved as regular PDF files. But how much longer they can be saved is unclear. PDF 1.0 was first copyrighted in 1985, and can theoretically still be read with a contemporary PDF reader.

What's Inside

    • The lowdown on replication appliances

      Operating system- and storage array-agnostic, replication appliances give companies increased flexibility to address one-time and continuous data replication needs, while allowing applications to continue processing without data loss or to recover with minimal downtime.

    • Backup outsourcers think small

    • Storage salaries increase

      The results for Storage's annual salary survey are in and storage professionals report salary growth. While the increases over last year are modest, they do represent the third straight year that our exclusive survey has shown an increase in storage salaries.

    • 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. Encryption can solve the problem, but implementing tape encryption isn't so easy, as performance issues could impact backup windows.
