摘要： A method is performed 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(s) of the at least one of the objects based on the scan of the index. The method further includes de-duplicating the redundant replica(s), and updating the index to reflect the status of the redundant replica.

摘要： A method performed by two or more devices of a group of devices in a distributed data replication system may include receiving a group of chunks having a same unique temporary identifier, the group of chunks comprising an object to be uploaded; creating an entry for the object in a replicated index, the entry being keyed by the unique temporary identifier, and the replicated index being replicated at each of the two or more devices; and determining, by an initiating device of the two or more devices, that a union of the group of chunks contains all data of the object. The method may also include calculating a content-based identifier to the object; creating another entry for the object in the replicated index, the other entry being keyed by the content-based identifier; and updating the replicated index to point from the unique temporary identifier to the content-based identifier.

摘要： A method may be performed by a device of a group of devices in a distributed data replication system. The method may include storing objects in a data store, at least one or more of the objects being replicated with the distributed data replication system, and conducting a scan of the objects in the data store. The method may further include identifying one of the objects as not having a reference pointing to the object, storing a delete negotiation message as metadata associated with the one of the objects, and replicating the metadata with the delete negotiation message to one or more other devices of the group of devices.
