How does SAP HANA support high availability?

SAP HANA supports high availability primarily through system replication and robust backup/recovery strategies. System replication allows for the real-time duplicating of data from the primary system to a secondary system. This ensures that in the event of a failure, the secondary system can take over with minimal downtime, allowing for continuous availability of services.

Backup and recovery strategies further enhance availability by ensuring that data can be restored to a consistent state after a failure or crash. These strategies include full and incremental backups, which can be utilized to recover data without significant data loss. Together, these features are critical in enabling organizations to maintain business continuity, minimize downtime, and safeguard against data loss.

The other options do not specifically address high availability in the context of SAP HANA. Scheduled maintenance and updates (the first choice) focus more on system upkeep rather than real-time availability. Customer data analytics (the second choice) pertains to data analysis rather than availability strategies, while user activity logging and tracking (the fourth choice) are important for auditing and monitoring but do not contribute directly to the high availability of the SAP HANA system.
