Abstract
Verifying a file in a system with duplicate segment elimination is disclosed. A data file is segmented into a plurality of distinct data segments, and a checksum is computed for each of the plurality of distinct data segments. A constructed data file checksum is constructed from the checksums of each of the plurality of distinct data segments, and, it is determined if a checksum of the data file is the same as the constructed data file checksum.
