Abstract

Techniques for data deduplication are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for data deduplication comprising receiving a write request for a unit of data, generating a fingerprint for the unit of data, transmitting at least a portion of the fingerprint to a plurality of deduplication monitors, performing the write request using an indicator indicating a location of a previously stored unit of data having a fingerprint matching the transmitted at least a portion of the fingerprint if a response indicating the previously stored unit of data having the fingerprint matching the transmitted at least a portion of the fingerprint is received from at least one of the plurality of deduplication monitors, and performing the write request using the unit of data if no response is received.
