What Needs to Be Backed Up?

The PRD Instance

Daily backup should be made for these SAP specific directories:

/usr/sap/
/sapmnt/
/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/ 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.
