Configuring the backup user and hdbuserstore
You should configure a dedicated database user within the HANA database to run the backup operations with Snap Creator. In a second step, you should configure a SAP HANA userstore key for this backup user. This userstore key is used within the configuration of the Snap Creator SAP HANA plug-in.
The backup user must have the following privileges:
-
BACKUP ADMIN
-
CATALOG READ

-
At the administration host, the host where Snap Creator got installed, a userstore key is configured for all database hosts that belong to the SAP HANA database. The userstore key is configured with the OS root user: hdbuserstore set keyhost 3[instance]15 userpassword
-
Configure a key for all four database nodes.
