ABSTRACT:
A system for minimizing downtime in an appliance-based business continuance architecture is provided. The system includes at least one primary data storage and least one primary host machine. The system includes an intercept agent to intercept primary host machine data requests, and to collect information associated with the intercepted data requests. Moreover, at least one business continuance appliance in communication with the primary host machine and in communication with a remote backup site is provided. The appliance receives information associated with the intercepted data requests from the intercept agent. In addition, a local cache is included within the business continuance appliance. The local cache maintains copies of primary data storage according to the information received. Furthermore, the remote site is provided with the intercepted data requests via the business continuance appliance, wherein the remote site maintains a backup of the primary data storage.
