We live in a data-dependent world and the importance of backing up your mission-critical data, and being able to keep working in the case of a disaster, is at an all-time high. One of the main concerns is business continuity; companies rely on their information systems to run their operations. If a system becomes unavailable, company operations may be impaired or stopped completely. It is necessary to provide a reliable infrastructure for IT operations, in order to minimize any chance of disruption. Information security is also a concern, and for this reason a data center has to offer a secure environment which minimizes the chances of a security breach. A data center must therefore keep high standards for assuring the integrity and functionality of its hosted computer environment. It generally includes getting a secure copy of your data backed up. Disaster recovery is the area of security planning that deals with protecting an organization from the effects of significant negative events like crippling cyber-attacks and equipment failures and other natural disasters like earth quake or hurricane.
