The evolution of data deduplication technology continues
This article is part of the Storage magazine issue of April 2013
Data deduplication technology for backup has evolved enormously in the last decade, and it's poised to go beyond just backup. Get Arun Taneja's thoughts on the subject. New technologies come to market as value-add features for existing mainstream products that are then later merged into these products. It's often the only way a new vendor can bring a product to market, like what happened with data deduplication technology. In the early 2000s, data deduplication came in the form of appliances from companies like Data Domain, Diligent Technologies, ExaGrid Systems, Quantum and Sepaton. The appliances worked in conjunction with existing backup software and the value proposition was simple: install the appliance, point the backup software to it and instead of backing up to tape the backup app would stream the data to the appliance. Backups and restores got faster and more reliable, and with deduplication, disk costs were close to that of tape. The market for the appliances soared in terms of revenue and acceptance. But why not merge...

Features in this issue
Cloud storage, virtualization and the relentless growth of unstructured data have all contributed to a rethinking of the way storage architectures are packaged and presented.
Cloud backup providers have grown up from their consumer product roots and now offer services that can meet the needs of enterprises. Here's what you need to know.
Poor provisioning and a lack of effective capacity management tools leads to underused storage systems. New tools and improved processes can make storage efficiency a reality.
Backup is never going to be easy, but new technologies and processes are helping storage pros overcome the backup problems that have plagued them for years.
Columns in this issue
Storage technology may not seem to be moving very quickly when measured by old criteria. But a new perspective shows the data storage industry is developing quite briskly.
With few standards and storage array vendors not inclined to give up their proprietary ways, managing data storage has become tougher than it should be.
Although the role of tape in traditional backup operations might be diminishing, it still has a place in long-term data retention and even cloud storage services.
