Final answer:
HSM, or Hierarchical Storage Management, is the backup method that enables continuous online backup with optical or tape jukeboxes, providing near real-time data protection.
Step-by-step explanation:
The backup type that provides continuous online backup and can be set up to provide the closest version of available real-time backup using optical or tape jukeboxes is HSM (Hierarchical Storage Management). This technology automates the movement of data between high-cost and low-cost storage media, ensuring that the most frequently accessed data is kept on the faster, more expensive media, while less frequently accessed data is moved to slower, cheaper media. The system's ability to provide near real-time backups makes it especially useful for organizations that require constant data protection.
HSM is a data storage technique that automatically and transparently moves data between different storage media based on its access frequency and importance. It uses optical or tape jukeboxes to store less frequently accessed data
