The SAP utilities BRBACKUP/BRARCHIVE can be called directly from the UNIX command level, using the SAPDBA menu (see Backing up the Database, Archiving the Offline Redo Logs), or from the R/3 System through the CCMS (see the online help of the Computing Center Management System).

BRBACKUP/BRARCHIVE do not use a graphical user interface in a UNIX environment. You can run them in any UNIX window and under any shell.

Both programs use standard commands for backing up the relevant files on a volume:

• cpio for backup to tape, cp for backup to disk if you are working with file systems.

• dd for backup of raw devices on tape or disk

BRBACKUP/BRARCHIVE must be configured. Some of the parameters for the initialization profile init<DBSID>.sap (see Description of Parameters) are described below.

The default configurations of both programs require online user interaction in several places. You can also run the programs without interaction - see Unattended Backup.

• BRBACKUP saves objects in the database (in accordance with the selected options):

You can also use BRBACKUP to back up non-database files and directories. See Backing up Non-Database Files and Directories.

• BRARCHIVE normally archives the online redo logs that ORACLE backs up in the archiving directory (offline redo log files) to tape. It is also possible to back up the offline redo log files to disk for special purposes (for example in a parallel server configuration).

• BRBACKUP/BRARCHIVE also backs up the following files to the volume (when database objects or offline redo log files are backed up) or to the first directory named in backup_root_dir for a backup of database files to disk:

• A copy of profile init<DBSID>.ora , init<DBSID>.dba (OPS: init.ora - /init.dba profiles of all the involved ORACLE instances)
• A copy of profile init<DBSID>.sap
• The main log of SAPDBA reorg<DBSID>.log , the structure log struct<DBSID>.log (OPS: script create_raw_links )
• The detail BRBACKUP/BRARCHIVE log
• The summary BRBACKUP/BRARCHIVE log (OPS: the summary logs of all the involved ORACLE instances)

• BRCONNECT monitors the database during a BRBACKUP process. See Monitoring the Database Status with BRCONNECT During a BRBACKUP Backup. BRTOOLS is a utility that is internally called by BRBACKUP and BRRACHIVE. See BRTOOLS. Neither program is called directly by the user; they are only called by the appropriate utilities.
