Deduplication Storage for Fast, Reliable Network-Based Disaster Recovery

Challenges

Natural disasters underscore the fallibility of tape-based backup strategies commonly used for disaster recovery. These strategies are inadequate because they require too much human intervention for effective management of large of amounts of data and are prone to loss or theft. In addition, Gartner estimates, one in 10 recovery images on tape is, in fact, unrecoverable.

Yet, backup-to-disk methods have not had a major impact on tape-based disaster recovery practices. Because of the cost of disk has historically been higher than that of tape, disk has been used primarily as a cache — or staging site — for a tape library infrastructure. In addition, disk-based disaster recovery strategies, such as network-based replication, have been too costly because of the amount of bandwidth needed for the large volumes of data.

What’s been missing is the technology to move backup data efficiently and economically over networks, to electronically vault the backup data to offsite storage and to meet long-term retention requirements.

Solution

Data Domain nearline storage systems have been designed from the ground up to optimize data protection and disaster recovery (DR) performance.

Data Domain high performance deduplication technology dramatically reduces the volume of backup and archive data to be transferred. By cutting the network bandwidth requirements up to 99%, Data Domain systems enable network-efficient offsite replication for disaster recovery, reducing or eliminating the need for tape backup.

Data Domain simplifies disaster recovery with:

  • Lower Cost of Operations. By decreasing the amount of data sent over a WAN by 99% or more, thereby reducing time and bandwidth costs.
  • Seamless Integration with Existing Infrastructure. Data Domain systems work with all leading backup applications, so there is no need to change the existing network infrastructure or backup policies.
  • Improved Recovery Time vs. Tape. Data can be recovered locally from the onsite Data Domain system or over the network from a replica system. This eliminates the time and cost of waiting for tapes to be delivered by truck, searching for the right set of tapes and mounting delays.

By replacing tape-based backup systems, Data Domain dramatically improves the speed and efficiency of disaster recovery and eliminates tape, trucks, unnecessary delays, and security risks.
