Abstract:
A method 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 comprising the steps of:generating at least one synchronization plan for the replicas for managing the synchronization therebetween, the sync plan comprising 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; and synchronizing at least one individual data unit in the first replica with a corresponding individual data unit in the second replica, in accordance with the sync plan, wherein the synchronization and conflict resolution actions have a capability of comprising different conflict resolution actions for different levels of the replicas and for different synchronizations between the replicas.
