Abstract: A system comprising a memory storing a set of instructions executable by a processor. The instructions being operable to monitor progress of an application executing in a first operating system (OS) instance, the progress occurring on data stored within a shared memory area, detect a failover event in the application and copy, upon the detection of the failover event, the data from the shared memory area to a fail memory area of a second instance of the OS, the fail memory area being an area of memory mapped for receiving data from another instance of the OS only if the application executing on the another instance experiences a failover event.
