In the mobile environment, weak consistency replication of shared data is the key to obtaining high data availability, good access performance, and good scalability. Therefore new class of consistency models, called session guarantees, recommended for mobile environment, has been introduced. Session guarantees, called also client-centric consistency models, have been proposed to define required properties of the system regarding consistency from the client's point of view. Unfortunately, none of proposed consistency protocols providing session guarantees is resistant to server failures. Therefore, in this paper checkpointing and rollback-recovery protocol rVsMW, which preserves monotonic writes session guarantee is presented. The recovery protocol is integrated with the underlying consistency protocol by integrating operations of taking checkpoints with coherence operations of VsSG protocol.
