Abstract

Performance of a checkpointing based multiple fault tolerance is low. The main reason is overheads associate with checkpointing. A checkpointing algorithm can be improved by improved storing strategy and checkpointing scheduling. Improved storage strategy and checkpointing scheduling will reduce the overheads associated with checkpointing. Performance and efficiency is most desirable feature of recovery based on checkpointing. In this paper important critical issues involved in fast and efficient recovery are discussed based on checkpointing. Impact of each issue on performance of checkpointing based recovery is also discussed. Relationships among issues are also explored. Finally comparisons of important issues are done between coordinated checkpointing and uncoordinated checkpointing.
