Data de-duplication specialist Data Domain has brought out a compact version of its storage appliance, called the DD120. Data Domain's technology is designed to reduce the amount of data that has to be backed-up or replicated, by eliminating redundancy.

The DD120 can be managed remotely, and is specifically designed to replicate data from remote locations to a datacentre hub for consolidated tape operations and off-site disaster recovery, the company said. It provides up to 150GB/hour of in-line storage throughput, and up to 18TB of logical capacity in a 1U chassis.

As well as automated data replication, the $12,500 (£6400) device can support backup and nearline software by emulating a CIFS or NFS file-server, or via the Symantec/Veritas NetBackup OpenStorage (OST) interface. It runs the same operating system as Data Domain's bigger appliances.

"This is a great option for distributed enterprise sites who would normally consider a tape autoloader but hate the hassle," claimed Brian Biles, Data Domain's product management VP. "They no longer have to make sure they have an administrator to replace the tapes and get them on a truck on time. With the DD120, storage and transport are automated, and management can be centralised."

Biles added that the DD120 includes as standard the company's Replicator software, which is an optional add-on for other models. This means that Data Domain's replication and de-duplication technologies can work together to greatly increase network bandwidth efficiency, making it cost-effective to replicate data across a WAN, he said.

De-duplication has mainly been seen as a datacentre technology, thanks to the amount of storage and processing involved. Smaller devices such as the DD120 could allow the technology to be applied much more widely, said Steve Duplessie, senior analyst at the Enterprise Strategy Group.

"Data Domain is extending its reach, enabling customers to put this technology out at remote offices and consolidate corporate data back to a central location," he commented.
