NetBackup for SAP backup scripts
If you configured a policy for automatic scheduling, you also need to specify backup scripts to be run automatically. You can either create your own scripts or you can modify one or more of the scripts that are included in the following location(s):
Windows:
install_path\NetBackup\DbExt\SAP\samples
UNIX or Linux:
/usr/openv/netbackup/ext/db_ext/sap/scripts/sap_oracle
/usr/openv/netbackup/ext/db_ext/sap/scripts/sap_maxdb
Table: NetBackup for SAP scripts shows the sample scripts.
Table: NetBackup for SAP scripts
Script name | Used by (underlying database) | Comments |
|---|
sap_offline_backup
sap_offline_backup.cmd
| Oracle without RMAN
| Issues a brbackup command and performs a whole offline database backup.
When initiated from an automatic schedule, the NetBackup bphdb process will set these variables into the environment, for use by the script and/or SAP backint interface. They identify the master server and policy that caused the script to be executed. UNIX/Linux: $SAP_SERVER $SAP_POLICY
Windows: %SAP_SERVER% %SAP_POLICY%
If the script is initiated from the client host, these variables can be set into the environment manually. On UNIX/Linux, the variables should be exported after being set.

sap_online_backup.cmd
sap_online_backup
| Oracle without RMAN
| Issues the brbackup and brarchive commands and performs a whole online database backup followed by an offline redo log backup.
|
sap_redo_log_backup
sap_redo_log_backup.cmd
| Oracle without RMAN
| Issues the brarchive command and backs up the offline redo log files.
|
sap_rman_backup
sap_rman_backup.cmd
| Oracle with RMAN
| Issues the brbackup command to perform either an RMAN incremental level 0 or incremental level 1 cumulative backup depending on whether the script was initiated from an Automatic Full or Automatic Cumulative schedule. If this script is to be initiated from the client, add logic to set the SAP_FULL or SAP_CINC variable appropriately. Otherwise the script will exit with status 0 without taking a backup.
|
sap_maxdb_backup
sap_maxdb_backup.cmd
| MaxDB
| Issues a dbmcli command and uses the specified backup medium to perform either a full or cumulative incremental backup depending on whether the script was initiated from an Automatic Full or Automatic Cumulative schedule. If this script is to be initiated from the client, add logic to set the SAP_FULL or SAP_CINC variable appropriately. Otherwise the script will exit with status 0 without taking a backup.

If you decide to use these scripts, customize them for your environment.
Always specify the correct script when configuring automatic backups or when starting operations through NetBackup. NetBackup for SAP does not generate an error if a restore script is used for a backup operation or a backup script is used for a restore operation.
All scripts must be stored and run locally. One recommendation is that scripts should not be world-writable. Scripts are not allowed to be run from network or remote locations. Any script that is created and saved in the NetBackup db_ext (UNIX) or dbext (Windows) location needs to be protected during a NetBackup uninstall.
