1.The backup session can be started using the Data Protector GUI, or interactively using the SAP R/3 utilities.

If the backup session is started using the Data Protector User Interface (or using the scheduler), then the Backup Session Manager (BSM) is started. The BSM then reads the appropriate Data Protector backup specification, checks if the devices are available, and starts the omnisap.exe program on the SAP R/3 Database Server.

The omnisap.exe program exports the appropriate environment variables and starts either the BRBACKUP or BRARCHIVE utilities. These utilities then initiate the first backint command to back up the Oracle Target Database’s data files and the control files (BRBACKUP) or to back up archived redo log files (BRARCHIVE).

If the backup is started interactively using the SAPDBA program, then the BRBACKUP or BRARCHIVE utilities are started directly.

2.BRBACKUP does the following:

•Automatically changes the state of the Oracle Target Database (opened or closed), according to the backup type (online or offline).

•Switches the Oracle Target Database to the ARCHIVELOG mode before the backup.

The archived redo log files are written to the archiving directory by Oracle and are backed up later using BRARCHIVE.

•Writes the BRBACKUP log during the backup session, with information about the backup file and the backup ID. These logs must be available in order to determine the location of the database files and archived redo log files during restores.

•Sets the tablespace mode (BEGIN / END BACKUP) in the case of online backup using backint.

In this way, the SAP R/3 puts the tablespace in backup mode just before it is backed up, and puts the tablespace back in normal mode immediately after the backup is completed. The tablespaces are therefore in backup mode for a minimal amount of time.
