There is provided a method and system for performing synchronization between a first replica associated with an application in a first computer processing device and a second replica associated with the application in a second computer processing device. The method includes the step of generating a synchronization plan for the replicas for managing the synchronization therebetween. The sync plan includes data structure information corresponding to data structures of the replicas, storage access information for enabling access to each individual data unit within the data structures of the replicas, and synchronization and conflict resolution actions for specifying actions to be taken for each individual data unit with respect to the synchronization and any conflicts resulting therefrom. At least one individual data unit in the first replica is synchronized with a corresponding individual data unit in the second replica, in accordance with the sync plan.
