Organisations turn to off-site data replication

Want to protect data from natural disasters.

Seventy-two percent of organisations want to do more off-site data replication, according to a February 2013 commissioned study conducted by Forrester Consulting on behalf of Silver Peak Systems.

This demand for off-site data replication is due to an increase of data being stored by businesses and the need to protect it from natural disasters.

About two-thirds (66 percent) of businesses are limited by their wide area network (WAN) performance, and this is the reason why they are unable to fully utilise off-site data replication.

Growth in data volumes and replication distances has made it difficult to design and implement an efficient and reliable disaster recovery (DR) plan. 

Sixty-five percent of businesses were found to have more than 100 terabytes of data company-wide, and 39 percent have more than a petabyte. Data replication takes too long for 54 percent of the respondents and 44 percent are not meeting their recovery time and recovery point objectives.

Upgrading data replication plans

Thirty-four percent of data is not replicated at all and this leaves data at risk. Fifty-three percent have prioritised to upgrade their current DR plans within the next 12 months.

Seventy-six percent said it was important or very important for off-site replication acceleration to be low-cost and easy to configure and manage.

Seventy-two percent of the respondents are searching for a solution that requires no changes to the existing network configuration. 

Recent advances in virtualisation technology can help the delivery of a replication acceleration solution that is software-based, says the study entitled "WAN Acceleration Fast-Tracks Data Protection And Disaster Recovery."

"As this study points out, data acceleration software is a proven method to overcome performance challenges for long distance off-site replication," said Rick Tinsley, president and CEO of Silver Peak. "By deploying Silver Peak's Velocity solution for replication, enterprises can easily meet their RPOs, lower disaster recovery costs, and extend distances between replication sites."
