摘要：By checkpointing and restoring a user application process, that includes avolatile state and a persistent state, recovery of an application process from thecheckpoint position is possible. Specifically, a volatile state is checkpointed in acheckpoint position. Next, the persistent state is monitored to detect a file operationfollowing a checkpoint position that will modify the persistent state. Then, portions ofthe persistent state are checkpointed if a modification of the persistent state is about tobe performed. Then, a recovery to the checkpoint position can be performed such thatmodifications to the persistent state since the checkpoint position are undone. Thisallows for resumption of the user application process from the checkpoint position.
