ABSTRACT:
For use with a central database associated with a server of a network, the central database having distributed counterparts stored in volatile memories of clients of the network to allow operations to be performed locally thereon, the central database further having multiple checkpoints and a stable log stored in the server for tracking operations on the central database to allow corresponding operations to be made to the multiple checkpoints, the stable log having tails stored in the volatile memories to track operations on corresponding ones of the distributed counterparts, the distributed counterparts to corruption, a system for, and method of, restoring a distributed counterpart stored in one of the volatile memories. The system includes: (1) a checkpoint determination controller that determines which of the multiple checkpoints is a most recently completed checkpoint and copies the most recently completed checkpoint to the one of the volatile memories to serve as an unrevised database for reconstructing the distributed counterpart and (2) an operation application controller that retrieves selected ones of the operations from the stable log and a tail corresponding to the distributed counterpart and applies the operations to the unrevised database thereby to restore the distributed counterpart.
