A data storage system includes storage and a global enumerator. The storage stores data chunks, object level metadata associated with portions of the data chunks, and chunk level metadata associated with respective data chunks. The global enumerator obtains a data access request that includes a metadata characteristic; in response to obtaining the data access request: matches the metadata characteristic to at least one of the data chunks based on at least one selected from a group consisting of the object level metadata and the chunk level metadata; and provides a response based on the at least one data chunk of the data chunks in response to the data access request.
