Abstract

Example implementations relate to deduplication operations in a storage system. An example includes receiving a stream of data units to be stored in a persistent storage of a deduplication storage system; loading a first container index into the memory to index one or more data units included in the stream; updating the first container index to indicate a storage location of a first data unit included in the stream; reading a manifest list in the first container index to identify a first manifest indexed by the first container index; and, while the first container index remains loaded in the memory to index the one or more data units, in response to a determination that the identified first manifest is included in the first backup item that has been marked for deletion, decrementing a reference count of a second data unit.
