SAP HANA Backup/Recovery Overview
SAP HANA holds the bulk of its data in memory for maximum performance, but it still uses persistent storage to provide a fallback in case of failure. After a power failure, the database can be restarted like any disk-based database and returns to its last consistent state. To protect against data loss resulting from hardware failure, backups are required. Both native backup/recovery functions, an interface for connecting 3rd party backup tools and support for storage snapshots are available. For recovery, SAP HANA offers many different options, including point-in-time recovery.
