Abstract

Storage using resemblance of data segments is disclosed. It is determined that a new segment resembles a prior stored segment. The prior stored segment comprises a segment stored previously from any location in an input data stream. A delta between the new segment and the prior stored segment is determined. A representation of the new segment based at least in part on the delta is stored.
