What is the default backup retention policy for the Autonomous Container Database?

The default backup retention policy for the Autonomous Container Database is set to 7 days. This means that when you create an Autonomous Container Database, Oracle Cloud Infrastructure automatically retains backups for a week. After this period, older backups are eligible for deletion, ensuring that you have a consistent and manageable amount of backups without consuming excessive storage.

This retention policy is designed to balance recovery needs while minimizing costs. Seven days of backups typically provides sufficient time to recover from accidental data loss or corruption without overwhelming the storage resources. Organizations can adjust this retention policy based on their specific requirements, allowing for greater flexibility in managing their data protection strategy.
