ABSTRACT:
A method for tracking modified pages is provided. The method is utilized in a fault-tolerant system, the fault-tolerant system comprising a first computer system and a second computer system. The method involves copying a memory from the first computer system to the second computer system at a first point in time. Between the first point in time and a second point in time, a scheduler tracks processes that execute on the first computer system in a harvest list. After the second point in time, the processes that made changes to the memory between the first and second points in time are retrieved. The changes to the memory are then copied to the second computer system and the changes are applied to the memory of the second computer system.
