IT companies that provide data security services often regard disaster prevention as separate from disaster recovery, though clearly, the two functions are closely related in many ways. Disaster recovery is defined as those software tools, policies, and procedures that allow a business enterprise to deal with downtime and recover from it. Disaster prevention, on the other hand, seeks to reduce the risk of downtime occurring in the first place. Both services are necessary if a business is to have the best chance possible of avoiding IT events that will disrupt routines and cause issues with employee workflow.
Disaster Recovery Services
In broad terms, disaster recovery seeks to establish redundancies in data and operations so that systems can be brought online after a crash or other event with as little disruption as possible to the enterprise. Best practices include provisions for redundancies that are geographically separated so that, for example, a fire in a data center cannot destroy both originals and backups of important electronic resources including data, configurations, and application software.
Disaster recovery services generally include data replication using backups to repropagate needed information, application recovery and server recovery as well as regular assessment and testing of the disaster recovery plan itself. iCorps Technologies' Guardian is a good example of disaster recovery service.
Disaster Prevention Services
These services generally exist at both the configuration level and the data center level. Disaster prevention services include such functions as core networking, establishing and maintaining appropriate cooling system capacity, security, monitoring, and encryption of data that must be kept confidential either because of company policies or governmental regulations. iCorps' Managed Security and AM/PM advanced monitoring services are good examples of appropriate disaster prevention measures.
