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)
