If you backed up your Exadata database by using
bkup_api, you can manually restore that database backup by using the Oracle Recovery Manager (RMAN) utility. For information about using
RMAN, see the Oracle Database Backup and Recovery User's Guide for Release 18.1, 12.2, 12.1, or 11.2.
To restore an Exadata database from a managed backup, see Recovering an Exadata Database from Object Storage.
