Summary :
SAP HANA utilizes in-memory technology for optimal performance but depends on disk-based persistent storage for data resilience, requiring regular savepoints and log writings to secure data against power failures. Data backups, essential for protecting against disk failures, can occur while the database remains online with minimal system impact. The SAP HANA database backup and recovery feature, addressed in this note, covers frequently asked questions and provides directions to additional resources, without detailing the backup process for all potential SAP HANA components.
