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

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

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