Abstract: SsMirror, which is disk storage sub-system layer based snapshot system, supports full snapshot and incremental snapshot. This paperintroduces the system design principle as a whole, and then some pivotal data structures of this system and Copy-on-Write (COW) for processingwrite requests are analyzed. The performance factors are presented.
