Database backup should be available for 7 years for Oracle ERP Fusion SaaS Product

Oracle SaaS products have specific backup policies to retain it for maximum 60 days and this cannot be altered or adjusted as per customer’s scope or requirements.

There is an audit requirement where database backup is required to be available for 7 years and database can be restored on any day during the period of 7 years. We are using Oracle Cloud ERP fusion which is a SaaS product and doesn't have server access to schedule backup using RMAN script.
