Abstract(in English) Most previous checkpointing techniques assume the storage media are stable. The system cannot recover from failure when some failures occur in the media because the checkpoint data are lost. In this paper, we propose a media-failure-tolerant uncoordinated checkpointing technique. In the proposed technique, each process saves its checkpoint data into the media of other nodes in addition to its own medium. When media failure occurs, the failure is recovered by loading these copies. Moreover, we performed simulations to evaluate the recoverability of fixed mirror node techniques and rotational one-mirror (ROM) techniques which changes mirror node every times. The results show the ROM technique can effectively reduce mean rollback distances on double media failures with lower message frequency.
