— In the SAP parameter file, set:
backup_dev_type = rman_util
rman_channels = <number_of_channels>
rman_parms =
"ENV=(OB2BARTYPE=SAP,OB2APPNAME=<DB_Name>,
OB2BARLIST=<Backup_Specification_Name>)"
Before starting an incremental backup, ensure that the appropriate full
backup is done using the following option:
-m full (using BRBACKUP) or backup_mode=full (in the SAP
parameter file)

To start an incremental backup, specify the Incr mode in the Data
Protector GUI or the Incr mode in the CLI, as follows:
omnib -sap_list <SAP_Backup_Specification> -barmode incr
Manual Balancing of Files into Subsets
Manual balancing allows you to precisely tailor the performance of an
SAP R/3 backup by grouping files into subsets that are backed up in
parallel. Make sure that:
• You use only one file from the same hard disk at a time.
• The number of files in a subset is equal to or smaller than a
concurrency number, that is, the sum of concurrencies of all devices
configured in the backup specification.
• If you do not specify all the files, other files that need to be backed up
are added to the list automatically using the load balance option.
Before backup, this list of files is logged in the
<ORACLE_HOME>/sapbackup/.*.lst (UNIX systems) or
<SAPDATA_HOME>\sapbackup\*.lst (Windows systems) file.
• You specify the file subsets in the manual_balance section of the
Data Protector integration configuration on the Cell Manager in the
/etc/opt/omni/server/integ/config/SAP/<client_name>%<ORAC
LE_SID> (UNIX systems) or
