A three tiered data synchronization system including a client, an enterprise data server, a synchronization server, and a pre-fetch data store. The client can have an associated client data store and the enterprise data server can have an associated server data store. The synchronization sever can intermittently and bidirectionally synchronize data within the client data store with data within the server data store. The pre-fetch data store can maintains data specific to synchronization requests that is used by the synchronization server when performing synchronization operations responsive to detected synchronization requests. The data specific to synchronization request used by the synchronization server is stored within the pre-fetch data store before the corresponding synchronization requests are detected by the synchronization server.
