Abstract
An apparatus and method for synchronizing a snapshot image are provided. A synchronization page is detected based on whether a page fault is generated in a snapshot page that is part of a snapshot image and based on attributes of a process that generated the page fault. The detected synchronization page is reflected in the snapshot image at a specific time.
