Integrating SAP R/3 and Data Protector

Integration Concept

Integration Concept

This integration links SAP R/3 backup utilities (BRTOOLS) with Data Protector. SAP R/3 backup utilities provide an interface between an SAP R/3 Database Server and media management applications, like Data Protector. They enable the backup or restore of the following SAP R/3 data objects:

•data files

•control files

•online redo logs

•offline (archived) redo logs

•SAP R/3 logs and parameter files

Because SAP R/3 Database Servers run on top of Oracle databases, the SAP R/3 backup objects are very similar to those of Oracle. The main difference is that SAP R/3 backup utilities hide the database from Data Protector, which sees those objects as plain files.

Version 4.5 and higher of the SAP R/3 backup utilities allows Oracle data files to be backed up directly using the Oracle Recovery Manager (hereafter referred to as RMAN mode), as well as using the Data Protector Oracle Integration (hereafter referred to as the backint mode). This is very useful because RMAN supports incremental backups, and thus the backup time and the amount of backed up data can be significantly reduced.

SAP R/3 Backup SAP R/3 backup utilities are the following:

Utilities

•BRBACKUP

This utility performs online and offline backup of control files, data files, and online redo log files. Additionally, BRBACKUP saves the profiles and logs relevant for a particular backup session.

•BRARCHIVE

This utility performs backups of the offline (archived) redo logs, written by Oracle to the archiving directory.
