Integrating SAP R/3 and Data Protector

Integration Concept

3. The backint program obtains the SAP R/3 configuration from the Cell

	Manager, divides the files for backup into subsets (provided that the
	specified concurrency is greater than 1) and starts the sapback
	program for each subset. Each sapback process connects to the BSM,
	which then starts General Media Agents on the corresponding client
	systems and establishes a connection between the sapback processes
	and General Media Agents.
	Data transfer can begin at this point. The sapback processes read
	data from disks and send it to General Media Agents. The first
	backint program stops as soon as all sapback processes have finished
	and control is returned to the parent process, either the BRBACKUP
	or BRARCHIVE utility.
	The second backint command is initiated by either the BRBACKUP
	or BRARCHIVE command. This command attempts to back up the
	SAP R/3 log files and parameter files (in the case of BRBACKUP), or
	the archived redo logs (in the case of BRARCHIVE) that have been
	created since the first backint command.
	If new archived redo logs have been created, they are backed up and
	another backint command is started. Otherwise, the SAP R/3 log files
	and the parameter files are backed up, and the second backint
	program is started using BRBACKUP.
	Therefore, more than two backint commands may be initiated by
	BRARCHIVE, while there are only two backint commands initiated
	by BRBACKUP.
	If archive logs were backed up, omnisap creates a copy of the control
	files either in the directory defined by the SAPBACKUP variable, or
	in /var/opt/omni/tmp (on UNIX) or
	<Data_Protector_home>\tmp (on Windows) if the variable is not
	set. The control file is then backed up by the backint utility using
	sapbackup.
NOTE	The total number of sapback processes started in one session using Data
	Protector is limited to 256.
	4. General Media Agents finish transferring data when all the sapback
	processes are complete. When all of the General Media Agents have
	finished data transfer, the BSM waits for a timeout
