The ability to move source data from enterprise disk to secondary disk is known as which of the following?

Deduplication is a data reduction technique that eliminates redundant data copies to save storage space, not a method for moving data between different types of storage.

Storage tiering is the practice of classifying data and moving it to different storage media (tiers) based on its performance, cost, and availability requirements. Moving data from expensive, high-performance "enterprise disk" to cheaper, higher-capacity "secondary disk" for less frequently accessed data is a prime example of this optimization strategy.

Shared access refers to the ability for multiple systems or users to concurrently access the same data, not a process of data migration between storage tiers.

Multipathing is a technique that uses multiple I/O paths between servers and storage to enhance performance and fault tolerance, distinct from moving data between different storage types.
