Explanation:
A: Creating an On-Demand Backup by Using the bkup_api Utility
You can use the bkup_api utility to create an on-demand backup of a database deployment hosting a single-instance database or an Oracle Data Guard

configuration.
1. Connect as the opc user to the compute node. In a Data Guard configuration, connect to the compute node hosting the primary database.
2. Start a root-user command shell:
$ sudo -s
#
3. You can choose to have the backup follow the current retention policy, or you can choose to create a long-term backup that persists until you delete it:
• To create a backup that follows the current retention policy, enter the following bkup_api command:
# /var/opt/oracle/bkup_api/bkup_api bkup_start
• To create a long-term backup, enter the following bkup_api command:
# /var/opt/oracle/bkup_api/bkup_api bkup_start –keep
1. Exit the root-user command shell and disconnect from the compute node:
# exit
$ exit
D: If some activity you want to perform requires you to temporarily disable regularly scheduled backups, you can do so by removing the scheduling information from
the system-wide /etc/crontab file.
