Backup & Recovery In SAP Hana

 

Backup & Recovery

Every initial load it is recommended to take a backup of ‘data area’, ‘log area’, and ‘configuration files’.

Backup of data area: This is done from the persistent stage to the external backup   location

Backup of log area: This is the automatic activity by the system scheduler where we have to define the level of logs to be captured.

Backup of configuration files:   Here we have all landscape settings, DB settings, privileges settings, etc., in .INI file which is to be backuped manually.

To take backup the user should have two privileges

• Backup – ADMIN
• CATALOG – READ, Backup – Admin

Process for taking BACKUP

Log on to HANA Studio.

Right-click on DB System

Select the backup option

Provide the base path where you take back up

(Which is already defined in global .INI file)
