Abstract

Abstract: This paper analyzes commom snapshot technologies，and discusses the implementing of dependent snapshot system in detail.And then it shows an effective design for dependent snapshot called INSPUR_SNAP.By implementing the INSPUR_
SNAP in real environment，result shows it offers effective performance，and can be used in real environment.

Key words: storage system, copy-on-write, dependent, shared-COW-device, B+tree, RB-tree
