Abstract
Techniques are described for managing data storage and retrieval, such as by generating a hash value for a beginning and/or ending portion of a new data group to be stored, attempting to match each generated hash value to a plurality of hash values associated with other existing data groups that are already stored, and comparing the new data group and an identified existing data group to determine any identical extended initial or final portion of the two data groups. The new data group may then be stored as the portion unique to the new data group, along with a reference to the existing identical extended portion of the existing data group. The new stored data group may be later retrieved using the unique portion of the data group, along with the existing extended portions corresponding to other stored data groups for any stored references.
