Abstract
Disclosed herein are methods, systems, and processes to perform dual-mode deduplication based on backup history. A fingerprint of a data segment of a data stream is calculated and a determination is made as to whether the fingerprint of the data segment matches a corresponding fingerprint in a cache. If the fingerprint matches the corresponding fingerprint, another fingerprint of a subsequent data segment of the data stream is calculated. If the fingerprint does not match the corresponding fingerprint, a segment boundary of the data stream is calculated based on a hash value, a determination is made that a new fingerprint calculated based on the segment boundary does not match the corresponding fingerprint, segment boundaries and new fingerprints are calculated, and a determination is made that a first fingerprint matches another corresponding fingerprint in the cache.
