  • communicating, by a processor, a subset of signatures of first data associated with an object to a plurality of stores on which the object is distributed;

    in response to the communication, receiving, from each of the plurality of stores, a response including a number of signatures stored on the store that match the subset of signatures;

    selecting, by the processor, one of the plurality of stores to send remaining signatures of the first data based at least in part on the number of matched signatures stored on each of the plurality of stores and a pattern of data storage on the stores;

    sending the remaining signatures to the selected store;

    receiving, from the selected store, information indicating which of the remaining signatures match a respective signature on the selected store; and

    based on the received indication, sending, to the selected store for storage, chunks of the first data that are not stored on the selected store.
