HANA Database Administrator (DBA) Practice Exam

The feature associated with low-cost recovery aimed at zero data loss in SAP HANA is storage replication. Storage replication ensures that data is continuously replicated in real-time to a different location, providing a fail-safe mechanism against data loss due to system failures. This approach allows for immediate recovery of data without significant downtime, which is essential for maintaining business operations and ensuring data integrity.

Backups, while critical for data recovery, are typically point-in-time snapshots, meaning there could be some data loss between the last backup and a failure. System replication, on the other hand, involves replicating the entire database to a secondary system and is geared more towards high availability rather than just cost-effective recovery. Cloud storage integration pertains to utilizing cloud services for data storage but does not specifically focus on recovery with zero data loss in the same manner as storage replication.
