Abstract
Updating fingerprints for deduplicated data segments in a cluster network by calculating new fingerprint hash values using a new hash process. A new index mapping from the present hash process to the new hash process is created, as is a new fingerprint index mapping from the updated hash process to the containers. The process generates new fingerprints with the new fingerprint hash, and calculates the new fingerprint hash values of the new data segments using the new hash process. Relevant data structures are updated using the current fingerprint hash values with the new fingerprint hash values. New containers are created as needed to store the new fingerprint hash values. Old data elements like containers and fingerprints are deleted during the upgrading process to reduce space overheads.
