  • Fingerprint backward compatibility in deduplication backup systems
    Patent number: 11163748
    Abstract: Disclosed herein are methods, systems, and processes to optimize and manage fingerprint backward compatibility in deduplication backup computing systems. A new fingerprint is generated for a segment object stored in a data container based on a new fingerprinting process. A header file is modified by replacing an old fingerprint for the segment object based on an old fingerprinting process with the new fingerprint. An entry including information indicating an association between the old fingerprint and the new fingerprint is created in a fingerprint map file.
