I am trying to backup SAP HANA database which is in Azure VM by using Recovery Vault service. While running "msawb-plugin-config-com-sap-hana.sh" script file I am getting the error

Failed to determine SYSTEM_KEY_NAME: Please specify with the '--system-key' option.

Need a valid system key to create the backup key.

enter image description here

Please help me to resolve this error.

The script uses the command "runuser" (in my case ndbadm). When hdbuserstore is executed under the profile ndadm no keys is returned. You can copy the files SSFS_HDB.DAT and SSFS_HDB.KEY in the path returned by hdbuserstore LIST from a profile with valid files.

According to the prerequisites https://learn.microsoft.com/en-us/azure/backup/tutorial-backup-sap-hana-db#prerequisites, you have to create a key in the default hdbuserstore. You can create it by login as ndbadm:

su - ndbadm

and add the key:

/hana/shared/NDB/hdbclient/hdbuserstore set BACKUP YOUR_HOSTNAME:30013 SYSTEM YOUR_PASSWORD

Then as a root, run the script. After running the script, you can check again as the ndbadm user if the key AZUREWLBACKUPHANAUSER is there:

/hana/shared/NDB/hdbclient/hdbuserstore list

and delete your previously created key:

/hana/shared/NDB/hdbclient/hdbuserstore delete BACKUP

Refer to SAP Note 2853601 - Why is Nameserver Port Used in HDBUSERSTORE for SAP Application Installation.

In an MDC - nameserver port (e.g. 30013) is used in hdbuserstore instead of indexserver port (e.g. 30015) for a tenant DB.
