A system configured to generate a macro-fingerprint from at least one predefined set of summaries is provided. The system includes data storage storing a first predefined set of summaries associated with a first region of data, each member of the first predefined set of summaries characterizing data within the first region of data; and at least one processor coupled to the data storage and configured to: read the first predefined set of summaries; select at least one first member from the first predefined set of summaries based on a value of the at least one first member; and store the at least one first member within a first macro-fingerprint. The first region of data may have a first size indicative of a quantity of data included in the first region of data. The macro fingerprints are created from previously created smaller (micro) fingerprints without having to reread the data.
