PowerProtect Data Manager 19.15 SAP HANA User Guide

Backup failure with getPreferredNode error

An SAP HANA backup might fail with an error that reports a getPreferredNode failure.

To identify any faults in the system environment, perform the following actions:

1. Ensure that the saphostexec service is running.

2. Run the following command from the console, and ensure that the command output does not include any errors:

   /usr/sap/hostctrl/exe/saphostctrl -function ListDatabaseSystems

Backup failure with insufficient privileges error

An SAP HANA backup might fail with an error that reports insufficient privileges.

To identify any faults in the system environment, perform the following actions:

1. Ensure that the credentials of the database user account are recorded correctly in the protection policy setting.
2. Ensure that the database user account included the protection policy has not been locked out.

3. Ensure that the database user account included the protection policy has the BACKUP_ADMIN, BACKUP_OPERATOR, and CATALOG_READ privileges. The SAP HANA article Authorizations Needed for Backup and Recovery provides more details.

Missing duration value for centralized backup

A centralized SAP HANA backup succeeds, but the backup job duration at the asset level appears as 0 ms on the Step Log tab and Details tab in the PowerProtect Data Manager UI.

The Step Log tab and Details tab appear in the Job ID Summary window, which you can access by selecting Jobs > Protection Jobs and clicking the job ID next to the job name.

As a workaround, view the correct backup duration in the Duration column in the left pane that has a grid format.

Backup and delete issue with database authentication type of userkey

With an SAP HANA client version earlier than 19.6 and PowerProtect Data Manager server version later than 19.6, the SAP HANA backup and delete workflow fails for protection policies with the database authentication type of userkey.

Perform either of the following workarounds:

• Update the SAP HANA client to the latest supported version.
• Change the database authentication type to username/password.

Shortened retention issue with SAP HANA full backup

You might encounter an issue with retention of an SAP HANA full backup after the retention time has been shortened.

When you shorten the retention time of an SAP HANA full backup from time T1 to time T2, the retention time value remains at time T1. The full backup is not cleaned up at the expected time T2.
