Abstract
A method for use by a first device associated with a redundant second device includes issuing a synchronization request to a file system of the first device. The file system is configured to cache changes associated with a memory space of an application, the synchronization request causing the file system to send the cached changes to a driver of the first device The driver is used to commit the cached changes to a copy of the memory space of the application in order to cause the copy of the memory space of the application to match the memory space of the application. One or more changes made to the copy of the memory space of the application caused by committing the cached changes are identified. A change set identifying the one or more changes being made to the copy of the memory space of the application is created in a buffer and the change set transmitted from the buffer to the second device in order to synchronize an additional copy of the memory space of the application at the second device.
