PROBLEM TO BE SOLVED: To reflect the status of a redundant replica in a distributed data replication system.SOLUTION: A method is implemented by a device of a group of devices in a distributed data replication system. The method includes storing an index of objects in the distributed data replication system, the index being replicated while the objects are stored locally by the plurality of devices in the distributed data replication system. The method also includes conducting a scan of at least a portion of the index, and identifying a redundant replica of at least one of the objects on the basis of the scan of the index. The method further includes de-duplicating the redundant replica, and updating the index to reflect the status of the redundant replica. |
