Integrating SAP R/3 and Data Protector

Configuring an SAP R/3 Backup

You can perform two types of online backups as well as offline backups.

• To start an offline backup, specify the -t offline and -d util_file BRBACKUP options. You can alternatively specify backup_dev_type = util_file and backup_type = offline in the SAP parameter file.

• The two types of online backups differ according to the duration in

 

which tablespaces are in backup mode.

 

If the -t online and -d util_file BRBACKUP options are

 

specified, SAP R/3 puts all tablespaces in backup mode before the

 

backup begins, and puts them back into normal mode after the

 

backup. The same is achieved by specifying

 

backup_dev_type = util_file and backup_type=online in the

 

SAP parameter file.

 

If the -t online and -d util_file_online BRBACKUP options

 

are specified, SAP R/3 puts individual objects in backup mode before

 

the backup begins, and puts them back into normal mode after the

 

backup. The same is achieved by specifying

 

backup_dev_type = util_file_online and backup_type=online

 

in the SAP parameter file.

 

Refer to the SAP R/3 documentation for more information.

 

Backing Up Using Recovery Manager
Benefits

Version 4.5 and higher of the SAP R/3 backup utilities allows Oracle data

 

files to be backed up using RMAN mode. RMAN mode is in general

 

transparent to the user. The User Interface remains unchanged and

 

allows the use of new options. The most important benefit of RMAN

 

mode is that the underlying Oracle database can be backed up

 

incrementally.

 

The backup procedure using RMAN mode is very similar to the one for

 

the underlying Oracle database using the Data Protector Oracle

 

integration. The following restrictions must be taken into account when

 

RMAN is used directly:

 

• The RMAN stores information about backups in the recovery catalog.

 

For security reasons, this catalog should be kept in a separate

 

database. This requires more administrative work.
