- Abstract
- Snapshot has been key technology for data protection and disaster recovery. To support RPO (Recover Point Objective) and RTO (Recovery Time Objective) for data protection, multiple snapshots should be created in short period. In this paper we propose a multiple snapshots management method which solve the existing methods. In the proposed method, snapshots share common metadata and a snapshot volume. We show the efficiency of our proposed method through simulation.
