Abstract: Example implementations relate to deduplication operations in a storage system. An example includes receiving data units to be stored in a persistent storage of a deduplication storage system; generating a fingerprint for each received data unit; identifying a set of fingerprints to be stored in container indexes, the container indexes including metadata indicating storage locations of data units stored in the persistent storage of the deduplication storage system; storing the identified set of fingerprints in at least one container index; and loading fingerprint entries for the identified set of fingerprints in a root node of a fingerprint tracking structure, where the fingerprint tracking structure is to identify each data unit stored in the persistent storage of the deduplication storage system.
