Computer system fault recovery using distributed fault-recovery information

A target-computer system that uses distributed fault-recovery information for recovering from target-system faults, the target-computer system comprising:

• a source-system-identity storage module that coordinates storage of an identity of each source-computer system that the target-computer system has interacted with and which has logged target-system fault-recovery information, wherein the source-system-identity storage module coordinates storage of an identity of at least one proxy server used on be behalf of a least one source computer fix logging target-system fault-recovery information;
• a fault-recovery-information-retrieval module that retrieves the previously logged target-system fault-recovery information from at least one source-computer system based on the at least one stored identity of source-computer systems that the target-computer system has interacted with;
• and
• a fault-recovery module that uses the retrieved target-system fault-recovery information for recovering from a target-system fault.

A method of using distributed fault-recovery information for fault-recovery of a target-computer system, the method comprising:

• storing, outside the target-computer system, a plurality of identities of source-computer systems that have interacted with the target-computer system, wherein the plurality of identities of source-computer systems that have interacted with the target-computer system includes an identity of at least one proxy server that has logged target-system fault-recovery information on behalf of at least one source computer;
• retrieving previously logged target-system fault-recovery information from a plurality of source-computer systems based on the stored plurality of identities of source-computer systems that have interacted with the target-computer system;
• and
• using the retrieved target-system fault-recovery information for recovering from a target-system fault.
