Backup through script

Is there any script to schedule backup ,daily for linux system for sap oracle database.

for eg

Enter the daily schedule every night at 11:30 PM, you would enter:

#sudo crontab -e

@daily 30 23 * * * /usr/sap/<sid>/SYS/exe/run/brbackup -p init<sid>.sap -d disk -t online -m all -k yes -e 0 -1 E -u /

If there is any other script to schedule backup daily for sap in linux system.

Thanks in advance,
