Which NetApp technology frees up storage by moving inactive data to lower-cost tiers while preserving access?

• A. Cloud Volumes Service
• B. BlueXP tiering
• C. BlueXP backup and recovery
• D. Cloud Volumes ONTAP

Answer: (B)

Moving inactive data to cheaper storage while keeping it accessible is what data tiering does. NetApp BlueXP tiering provides policy-driven tiering across on‑prem and cloud storage, automatically identifying cold data and moving it to lower-cost tiers. Access stays intact because the system keeps the necessary metadata and references; when the data is read, it can be retrieved from the cheaper tier transparently to the user or application. This reduces space used on the primary storage and lowers costs without disrupting workloads. The other options touch on related capabilities, but the feature that directly describes tiering to free up storage while preserving access is BlueXP tiering.
