Huawei OceanProtect provides a multi-layered defense to ensure that backup data remains immutable and protected from ransomware attacks. To specifically prevent data tampering and deletion, the following technologies are employed:

WORM (Write Once, Read Many) (Option C): This technology ensures that once data is written to the backup storage, it cannot be modified or deleted by any user (including administrators) until the specified retention period has expired.

Secure Snapshot (Option A): These snapshots are protected by a " read-only " attribute and a retention lock. Unlike standard snapshots, secure snapshots cannot be deleted manually before they expire, providing a reliable point-in-time recovery source even if the primary backup is targeted.

Air Gap (Option B): By physically or logically isolating a copy of the data in an " Air Gap " zone that is disconnected from the network most of the time, Huawei ensures that the data is unreachable for tampering or deletion by attackers who have gained access to the production network.

Detection and analysis (Option D) is part of the solution, but its purpose is to identify an ongoing attack or infected files, rather than physically preventing the tampering or deletion of the data itself.
