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. As soon as there is any update and transaction, logs become active and get saved from the disk memory. In case of power failure, the database restarts like any other DB returning to the last save point log state.
