How often do I need to backup? In SAP


The PRD Instance

Daily backup should be made for these SAP specific directories:

      /usr/sap/<SID>
      /sapmnt/<SID>
      /usr/sap/trans on the TMS Domain Controller Server
      Any directories containing flat files that are used by the SAP instance

Daily backups should be made for these Oracle specific directories:

      /oracle
      Directory holding redo logs if not in the /oracle structure

Weekly backup should be made for these OS specific directories:

      Root
      /etc
      /dev

For Oracle, the entire /oracle directory should be backed up daily if there is only one Oracle Instance on the server, and each separate /oracle/<SID> directory if there is more than one instance on the server.

It is also recommended that a full offline image of the entire server be made before the monthly closing cycle.

The DEV and QAS Instances

Weekly backup should be made for these SAP specific directories:


      /usr/sap/<SID>
      /sapmnt/<SID>
      Any directories containing flat files that are used by the SAP instance

Weekly backups should be made for these Oracle specific directories:

      /oracle
      Directory holding redo logs if not in the /oracle structure

Monthly backup should be made for these OS specific directories:

      Root
      /etc
      /dev

For Oracle, the entire /oracle directory should be backed up daily if there is only one Oracle Instance on the server, and each separate /oracle/<SID> directory if there is more than one instance on the server.

It is also recommended that a full offline image of the entire server be made at the same time every month.
