Integrating SAP R/3 and Data Protector
Backing Up an SAP R/3 Database
Chapter 2 197
Backing Up an SAP R/3 Database
To run a backup of an SAP R/3 database, use any of the following
methods:
Backup Methods • Schedule a backup of an existing SAP R/3 backup specification using
the Data Protector Scheduler. See “Scheduling a Backup” on
page 198.
• Start an interactive backup of an existing SAP R/3 backup
specification using the Data Protector GUI or the Data Protector CLI.
See “Running an Interactive Backup” on page 200.
• Start an interactive backup on SAP R/3 Database Servers using
either the brbackup or the sapdba command. See “Using SAP R/3
Commands” on page 202.
NOTE If you use brbackup or sapdba to start a backup session, you do not
receive any Data Protector messages about the progress of the session.
Messages from the Data Protector backup session are logged in the Data
Protector database. SAP R/3 messages generated by the brbackup or
sapdba commands are logged to the Data Protector database only if Data
Protector is used to start the backup.
Duplicate SIDs Concurrent backups of systems with the same Oracle SID in the same
cell are not supported.
Backup Modes Configurable backup modes that were used in Data Protector versions
earlier than A.03.00 are not supported in the current version of Data
Protector. However, their functionality is now supported using
templates.
Incremental
Backups
Before starting an incremental backup, ensure that the appropriate full
backup is done using the following option (note that this is valid for SAP
tools version 4.5 and later):
-m full (using BRBACKUP) or backup_mode=full (in the SAP
parameter file).
