ABSTRACT:
An embodiment of a method of checkpointing a virtual memory for a process comprises: accessing a page table that correlates logical addresses for the process to physical locations; saving memory resident pages identified for the process from the page table; and saving disk swap pages identified for the process from the page table, the step of saving disk swap pages being performed after the step of saving the memory resident pages.
