Abstract:
1. A system for minimizing downtime in an appliance-based business continuance architecture, comprising: at least one primary data storage; at least one primary host machine, wherein the primary host machine can access data stored at the primary data storage; an intercept agent at the primary host machine to intercept data requests made to the host machine and to collect access patterns and statistics associated with the intercepted data requests, wherein the intercepted data requests include data read requests and data write requests; at least one business continuance appliance in communication with the intercept agent at the primary host machine and in communication with a remote backup site, wherein the business continuance appliance receives information associated with the intercepted data requests from the intercept agent; a local cache included within the business continuance appliance, wherein the local cache maintains copies of data associated the intercepted data requests, wherein the copies are maintained according to the access patterns and statistics received; and the remote backup site to be provided with the intercepted data requests via the business continuance appliance, wherein the remote backup site maintains a secondary copy of the data located at the primary data storage, whereby the data maintained by the local cache is utilized to provide a backup copy of data in the event of the primary site failing, without resorting to access of the remote backup site.
