A method and apparatus for continuous data protection is provided. In one embodiment, the method for continuous data protection comprises receiving a write request for writing at least one data segment to storage; computing, using at least one processor, a signature for the at least one segment; comparing, using at least one processor, the signature that is associated with the at least one segment with a plurality of data signatures for previously stored data segments; and processing the data segment in a manner dependent upon whether the signature matches any one of the plurality of data signatures.
