Which of the following is NOT a remote protection policy offered by System Manager?

The option that is not a remote protection policy offered by System Manager is backup and restore. This choice focuses on a data management method involving copies of data being stored separately for recovery purposes. While backup and restore solutions are critical for data protection, they typically operate at a broader data protection level and do not specifically fall under the category of remote protection policies.

In contrast, synchronous and asynchronous replication, as well as SnapMirror Business Continuity, are actively designed as remote data protection strategies. Synchronous replication ensures that data is written to both the primary site and the secondary site simultaneously, offering immediate failover capabilities. Asynchronous replication allows data to be copied to a remote site with a slight delay, facilitating long-distance data retention while minimizing the impact on performance. SnapMirror Business Continuity specifically addresses data replication in a manner that supports recovery and continuity of operations in the event of a disaster.

Thus, the distinction lies in the focused purpose of the options: backup and restore is centered on recovery and does not specifically highlight remote replication or active data protection policies like the others do.
