The state of backup dedupe
This article is part of the Vol. 10 Num. 6 August 2011 issue of Storage magazine
In a relatively short time, data deduplication has revolutionized disk-based backup, but the technology is still evolving with new applications and more choices than ever. Data deduplication technology identifies and eliminates redundant data segments so that backups consume significantly less storage capacity. It lets organizations hold onto months of backup data to ensure rapid restores (better recovery time objective [RTO]) and lets them back up more frequently to create more recovery points (better recovery point objective [RPO]). Companies also save money by using less disk capacity and by optimizing network bandwidth. Deduplication was first adopted by companies with tight backup windows and those looking to reduce tape usage. The primary considerations were seamless integration with incumbent backup apps and processes, and ease of implementation. In the next wave of adoption, concerns shifted to scaling capacity and performance. Vendors beefed up disk capacity, performance, network connectivity and system interfaces, and ...

Adoption of storage virtualization picks up as early obstacles to implementation are overcome. Mature products exist to deploy storage virtualization at the array or in the network
Storage technologies may sometimes seem a little stodgy and out of date, but there’s plenty of technical development going on at both the big storage vendors and smaller upstarts.
