Özet

This study presents preliminary results from a distributed checkpointing approach developed to be used with replicated state machines. Our approach takes advantage from splitting and storing partial execution history of the master state machine in a distributed way. Our initial results show that using such an approach provides less memory consumption for both the running replicas and the restoring replica in case of a failure. On the other hand for larger histories and larger number of replicas it also increases the restore duration as a major drawback.
