Why cannot the storage space be reclaimed from an expired tape when deduplication is enabled on the tape?
Products and versions:
The VTL with the deduplication function inside logically include the VTL space and the SIR space. After deduplication is performed on an expired tape, the deduplicated data is stored in the SIR space and the index is stored in the tape and the SIR index space. If the data pointed by the index is referenced by other tapes, the storage space of the expired tape cannot be reclaimed.
