Patent ID: 7246258

Claim:
A system for minimizing data resynchronization time after backup system component failures 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 at least one primary host machine to intercept data requests and collect information regarding the intercepted data requests; a summary log at the at least one primary host machine to maintain the collected information; at least one business continuance appliance in communication with the intercept agent and in communication with a remote backup site, wherein the business continuance appliance receives the collected information from the intercept agent; a local cache included within the business continuance appliance, wherein the local cache maintains the collected data; and the remote backup site to be provided with the collected data, wherein the remote backup site maintains a secondary copy of the data located at the primary data storage, whereby, the summary log is utilized to minimize resynchronization time in the event of the combined failure of the business continuance appliance and the remote backup site, wherein the configurable period of time is based on whether the data has been backed up to persistent storage by the remote backup site and further wherein the including of a timestamp on the collected information by the intercept agent is utilized to identify which information has been moved to persistent storage at the remote backup site.
