Access "CDP poised to replace traditional backup methods"

Published: 19 Oct 2012

We've witnessed major changes in data management during a decade of SAN evolution. Advances in disk capacity, huge reductions in the cost of disk and ever-developing tools have significantly changed the way data is managed. Today, we're able to provision and allocate storage online, create snapshots and local volume copies automatically, and replicate data across long distances. The technologies used to perform these tasks are far from "bleeding edge," but many have been widely adopted and are generally accepted as best practices for managing and protecting data. Compared to the pre-SAN era, the shift is quite dramatic. But amid this data management revolution, backup is a notable exception. Despite advances such as SAN-based shared tape drives and disk technology like virtual tape libraries, the backup process is fundamentally the same as it was 20 years ago. Backup remains a costly and highly intrusive batch operation that's prone to error and consumes an exorbitant amount of time and resources. Defining CDP "Continuous data protection (CDP) is a ... Access >>>

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.
