What you need to know about data dedupe tools for backup

This article is part of the Vol. 10 Num. 6 August 2011 issue of What you need to know about data dedupe tools for backup

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 also improved deduplication ... Access >>>
