Explanation
Hierarchical Storage Management (HSM) automates the migration of data across different storage tiers - typically from fast, expensive media (like disk) to slower, cheaper media (like tape or optical) - based on access frequency. It uses optical or tape 'jukeboxes' (automated robotic libraries) and WORM (Write Once, Read Many) media to provide continuous, near-online backup without manual intervention. The other options - HRM, HAM, and HIM - are fabricated acronyms that do not correspond to any real storage management standard.
