Abstract
Example implementations relate to deduplication operations in a storage system. An example implementation includes receiving a data page to be stored in a persistent storage of a deduplication storage system, and, in response to a determination that the data page includes the leading zero pad, performing a circular shift of the plurality of data blocks to generate a realigned data page that begins at a non-zero value portion. The example implementation further includes generating a fingerprint for the realigned data page, and comparing the generated fingerprint to a plurality of fingerprints included in metadata of the deduplication storage system. The example implementation further includes, in response to a determination that no matches are found between the generated fingerprint and the plurality of fingerprints included in the metadata, storing the realigned data page and the generated fingerprint in the persistent storage.
