1. A computerized method of replicating an object from a source local deduplication store to a remote server based on data already stored on the remote server to reduce the amount of duplicate data sent from the local deduplication store to the remote server, the method comprising:
sending, by the source local deduplication store to the remote server, a set of hashes for a source object to be replicated from the source local deduplication store to the remote server; receiving, by the source local deduplication store, data from the remote server including:
a set of object hashes representative of data in the source object that is already present on the remote server, anddata indicative of source object hashes that are not present on the remote server; identifying, by the source local deduplication store, portions of the source object that are not already present on the remote server based on the received data; and transmitting, by the source local deduplication store, the identified portions of the source object to the remote server to replicate the source object on the remote server so that only the portions of the source object not already present on the remote server are copied to the remote server to replicate the source object. |
