The mapping follows Huawei ' s separation of business continuity, data recoverability, and long-term retention.
The course states: “DR ensures business continuity. Backup focuses on data recoverability. Archiving is for long-term storage of cold data and regulatory compliance.”
Remote replication combined with BCManager eReplication addresses site-level disaster recovery, and Huawei states that BCManager provides one-click DR drill and switchover capabilities.
HyperMetro is the appropriate solution for storage-level continuity because Huawei defines it as an active-active storage solution using dual-write technology to provide service continuity and zero data loss.
When continuous availability must extend to the application layer, storage HyperMetro must be combined with an application cluster so that application processing itself can fail over seamlessly.
Finally, backup protects against logical corruption, accidental deletion, and malware-related damage because historical copies remain available independently of production data.
