Abstract: Example implementations relate to deduplication operations in a storage system. An example includes identifying a corrupt data unit included in a first snapshot; identifying a first manifest that references the corrupt data unit; identifying, based on the first manifest, a first container index that indexes the corrupt data unit; determining, based on the first container index, a set of candidate manifests; identifying, in the set of candidate manifests, a second manifest having a highest match score with respect to a first portion of the first manifest; and in response to a determination that the identified second manifest having the highest match score does not reference the corrupt data unit, replacing in the first manifest a reference to a corrupt data unit with a reference to a non-corrupt data unit referenced in the identified second manifest.
