Patent ID: 7065674

Claim:
A source-computer system that participates in fault recovery of a plurality of target-computer systems, the source-computer system having at least one source computer and comprising: a logging module that logs, within the source-computer system, target-system fault-recovery information for the plurality of target-computer systems, wherein the target-system fault-recovery information specifies a plurality of operations and outcomes describing interaction between a source computer within the source-computer system and the plurality of target-computer systems; and wherein, during fault recovery of the respective target-computer systems, the source-computer system provides to at least one of the plurality of target-computer systems a portion of the target-system fault-recovery information that pertains to the at least one of the plurality of target-computer systems, wherein the portion of the target-system fault recovery information includes log records that, when played back by the at least one target-computer system, caused the at least one target-computer system to return to a target-computer-system state that existed before occurrence of a target-computer-system fault for which fault recovery is being performed.
