A low overhead checkpointing and rollback recovery scheme for distributed systems
Zexiang Tong, Richard Y. Kain, Wei‐Tek Tsai · 2003
A major obstacle in implementing a rollback recovery scheme for fault tolerance in a concurrent distributed system is the domino effect. A low overhead checkpointing scheme is proposed to prevent this effect. Each process saves its state periodically. The state-save synchronization among processes is implemented by bounding clock drifts. A communication protocol that assures that all saved states are consistent is developed.>
