摘要： Embodiments described herein adapt static-image and clone technology to provide a simulated dynamic image to an application requesting a dynamic image. A storage system is configured to backup its file system by taking a first static image of the file system at a point in time. A clone of the first image may then be produced, the clone containing any subsequent changes to the file system and a reference pointer to the first image. A second static image of the clone is then produced. An application may request, from the storage system, an image of the file system. In response, the second static image may be presented to the application as a simulated dynamic image.
