MINIMIZATION OF RESYNCHRONIZATION TIME AFTER BACKUP SYSTEM FAILURE IN APPLIANCE-BASED BUSINESS CONTINUANCE ARCHITECTURE

摘要

PROBLEM TO BE SOLVED: To provide a resynchronization method for minimizing downtime in an appliance-based business continuance architecture.

SOLUTION: At least one primary data storage, a primary host, and an intercept agent intercepting data requests of the primary host, and collecting information associated with the data requests are included. A business continuance appliance is provided for communicating with the primary host and a remote backup site. The appliance receives the information associated with the intercepted data requests from the intercept agent. A local cache is included within the business continuance appliance. The local cache maintains copies of the primary data storage according to the received information. The remote site is provided with the intercepted data requests via the business continuance appliance, and it maintains a backup of the primary storage.
