ABSTRACT:
A recoverable virtual memory for a computer system takes periodic checkpoints which capture the state of the virtual memory. If a system failure occurs, the system can be rolled back to the checkpointed state and restarted. A mechanism for tracking which virtual pages are contained in the checkpointed state discards pages which have been modified since the checkpointed state was saved. Only versions of pages which are saved in the checkpointed state are used in the restore process.
