Post installation steps:

Create symbolic link of hdbbackint as follow:

1. Open putty session of SAP HANA system.

2. Log-in using adm user only. Do not use root user creating symbolic link.

3. Go to "cd /usr/sap//SYS/global/hdb/opt"

4. ln -s /bin/hdbbackint hdbbackint

Change data backup, log backup and catalog backup settings to backint using hana studio or by modifying global.ini file accordingly. Refer SAP HANA admin guide for this.

IMPORTANT: For multi host SAP HANA system, install Netvault client on each host and install plugin on each host. Installation directory path of Netvault on each host should be same. Symbolic link created from one host should reflect on all other hosts of SAP HANA.

Backup Job Initiation

It is done from the SAP HANA Studio only but Netvault shows the Jobs completed status in the Netvault UI

Restore Process

Highlight the data backup selection and click on ‘Check Availability’ to see if Netvault has the save set available for restore. (This is based on the retention)

Restore progress can be observed from the Netvault UI , Single restore job uses only one stream

Backing up and restoring data for SAP HANA is performed using SAP HANA utilities, such as SAP HANA Studio,
Cockpit, or HDBSQL; Maintenance and housekeeping operations, including deleting obsolete data backups and deleting obsolete log backups for SAP HANA are performed using SAP HANA utility backups and restores are not performed using the NetVault Backup WebUI.
When a backup job is triggered in SAP HANA, hdbbackint creates the job in NetVault Backup. You can use the
NetVault Backup WebUI to monitor the status of each job that hdbbackint initiates. After the job is finished, you
can continue to use the WebUI to review pertinent information.
