System and method for incremental change synchronization between multiple copies of data
 A system and method for incremental change synchronization among multiple copies of data is disclosed. To achieve the synchronization a genera synchronization model is used. The synchronization model establishes a one-way data flow path to allow incremental changes to be transferred from a copy of data that incorporates the incremental changes to a copy of data that does not yet incorporate the incremental changes. To achieve this one-way data flow path, the synchronization model uses an agent, a data collector, and a data synchronizer. The data collector collects incremental changes transferred to it and applies the incremental changes to a copy of data. A data synchronizer transfers incremental changes to a data collector. An agent controls the synchronization process by making a connection between a data collector and a data synchronizer and then directing the data synchronizer to transfer data to the data collector. If bidirectional data flow is necessary to achieve synchronization between two copies of data, a one-way data flow path is established first in one direction and after all incremental changes have been passed in that direction, a data flow path is established in the opposite direction to pass incremental changes in the opposite direction.
