1.What kinds of backup available in SAP HANA?

To learn more about insight of SAP HANA Backup and Review, you are recommended to read this document:

SAP HANA Backup and Recovery Overview (Presentation, source of screenshot below)

SAP HANA persists two types of data to storage: transaction redo logs, and data changes in the form of savepoints.

Data backups:

Full backup (Data and configuration for the whole HANA system instance)

Delta backup (Available since HANA SP10)

-Incremental backup (based on any latest backup)

-Differential backup (based on the latest full data backup)

Log backups: Automatic unless disabled.

In addition, starting with revision 70 SAP HANA database supports storage snapshots (see SAP Note 2039883).

2.Can I perform a backup for a specific schema instead of the whole HANA instance, then rename it for QA?

SAP HANA does support the export of schema, and import as a different name. However, this operation only export the data and objects(tables, triggers, procedures etc) of schema from database level, which doesn't assure the data consistency if transaction committed by other connection to the same schema whilst the schema is being exported.

It is recommended to export and import the schema through the SAP Business One Backup Service in SLD or Remote Support Platform. However, if you would like to conduct the schema export and import with SQL by manual, you should follow the note below when export and import schema.

Doing a schema backup is not the same as a full system backup. A full system backup is still required, see question 3 for more information.

3.Do I have to perform a full data backup(HANA instance backup) regularly?

Yes, like any DBMS, full data backups of the whole HANA instance should be performed regularly for disaster recovery.

After a full data backup, the log backups before the latest full data backup can be checked for consistency, then deleted safely if no recovery to the earlier stage required.

Without regular full data backup and deleting older log backup, the log backup may keep growing up to full disk, which may result in outage of SAP HANA system.

Option 1: (Recommended) perform an SAP HANA instance backup with RSP. Please refer to 5.How can I schedule SAP HANA backups?

Option 2: You can manually perform a backup with SAP HANA studio, or SQL command.
