About this release

The DR Series system is a high-performance, disk-based backup and recovery appliance that is simple to deploy and manage and offers unsurpassed Total Cost of Ownership benefits. Features such as innovative firmware and an all-inclusive licensing model ensure optimal functionality and provide the assurance of no hidden costs for valuable future features.

A purpose-built backup-to-disk appliance, the DR Series system provides advanced deduplication and compression technology to store data most efficiently. The DR Series hardware appliances are 2U, rack-based, system backup storage repositories, that include deduplication and compression technology in their operating systems. A virtual machine (VM) version is also available to provide robust, disk-based data backup capability on Virtual Machine host servers, while taking advantage of replicating to a deduplication-enabled appliance.
