Abstract
Approaches to efficiently creating a checkpoint of the process are described. In one approach, a method of performing a checkpoint operation on a process involves detecting a change in the contents of a memory page associated with the process. This change occurred after a preceding checkpoint operation. The method also involves modifying a data structure, at a location corresponding to the contents of that memory page.
