Abstract

A method of protecting data on a mobile computing device using a storage network by deploying to the mobile computing device, a synchronization agent and then associating a synchronization policy with the synchronization agent. The mobile computing device is monitored for at least one threshold event. Its determined that the threshold event has occurred which causes a request to initiate a data synchronization event to be transmitted. The response to the request is synchronizing the mobile computing device with the storage network.
