"According to our research, customers are more concerned with efficiency, citing cost, ease-of-integration, ease-of-use, and performance as top factors for selecting data deduplication. The Arkeia-Kadena approach of offering deduplication as an integrated backup solution promises to address all of these top issues.”

As the growth of enterprise data accelerates, organizations struggle to find more efficient ways to manage this data. One emerging approach to controlling data growth is data deduplication. Data deduplication technologies are especially relevant to backups because a large fraction of backups consists of duplicate data.
Data deduplication is a data compression technology that shrinks data volumes by identifying and eliminating redundant data. Deduplication gained a foothold in organizations by making possible "better" network-attached storage (NAS). The primary benefit of "better" NAS was reduced storage volumes--though cost savings were sometimes meager.
Deduplication promises to offer greater benefits when applied to backup by making backups faster and easier to manage, and by reducing the cost of complexity of deploying stand-alone deduplication technology.
Arkeia Software has acquired Kadena Systems to gain access to Kadena's next-generation data deduplication technology that is fast, efficient, and scalable. The Kadena approach of deduplicating data uses a block-grain, sliding-window, content-aware technology that is superior to traditional variable-block approaches.
The primary challenge for first-generation sliding-window implementations has been CPU load. Arkeia will introduce Kadena's proprietary next-generation progressive-matching technology to dramatically reduce the amount of CPU required to identify duplicate blocks. Kadena's technology is protected by a combination of granted patent and trade secrets. The first Kadena patent was filed in 2004 and the technology has proven fast and reliable for more than 6,000 end-user customers.
Arkeia Software plans to integrate Kadena’s proven deduplication technology to deliver source-side data deduplication in Arkeia Network Backup. Source-side deduplication is important in backup applications because it accelerates the backup process by reducing the amount of data that is transferred over the network and stored on disk. Faster backups permit shorter backup windows, minimizing resource contention with other applications. Source-side data deduplication is especially attractive in environments with large amounts of duplicate data, such as virtual environments.
