There are a number of ways to run backups for the SAP HANA system.
Execute a Backup Using HDBSQL
Executing the following HDBSQL command for a database (either tenant or SystemDB) will trigger a backup being run:
BACKUP DATA for <Database_name> using backint ('BACKUP_PREFIX')
Execute a Backup Using SAP HANA Studio
See the Protecting SAP HANA with VERITAS Netbackup for details on how to create a backint backup.
Execute a Backup Using SAP HANA Cockpit
SAP HANA Cockpit can be used to schedule and create manual backint backups. More information on using SAP HANA Cockpit can be found in SAP HANA Administration with SAP HANA Cockpit: Backup and Recovery.
