Abstract
Cluster storage is disclosed. A data stream or a data block is received. The data stream or the data block is broken into segments. For each segment, a cluster node is selected, and in the event that a similar segment to the segment is identified that is already managed by the selected cluster node, a reference to the similar segment and a delta between the similar segment and the segment is caused to be stored on the selected cluster node.
