"Knowledge is power, but it is only useful if it is shared!"


A sample backup schedule might look like:
1. Hourly - brarchive backup of archive logs
2. Daily - brbackup backup of full database
3. Monthly - file system backup of /sapmnt/, including SAP executables and profile data, and /oracle/SID/_/dbs & network ---making sure you get Oracle/SAP init files and network files (tnsnames.ora, listener.ora,\nnames.ora, etc., though you might have relocated these files elsewhere), & /usr/sap/trans directory.
4. Quarterly - Oracle export performed to tape.

This schedule is good enough for a small system landscape with an orgnanization. If the landscape is huge, then you need to re-think about how backup is done. An integration with Oracle RMAN is good for running incremental backup. This will reduce the number of media needed for running daily full online backup - storage optimization

-----------------------------------
SAP gives you standard Basis role :

SAP_BC_BASIS_ADMIN
SAP_BC_DB_ADMIN or SAP_BC_DB_ADMIN_ORA if you are using Oracle
SAP_BC_CLIENTCOPY
SAP_BC_BATCH_ADMIN
SAP_BC_TRANSPORT_ADMINISTRATOR
SAP_BC_SPOOL_ADMIN

copy that to ZSAP_BC_BASIS_ADMIN, ZSAP_BC_DB_ADMIN, ZSAP_BC_DB_ADMIN_ORA, etc. then modify that Zrole if you need to add or remove tcode and/or authorization objects. and finally assign to your consultant username.

but you have to monitor your consultant for what they did on your production server using STAD.
