Which product provides an add-on service to back up NetApp Cloud Volumes ONTAP volumes to public cloud object storage?

The correct answer is Cloud Backup Service, which seamlessly integrates with NetApp Cloud Volumes ONTAP to provide backup capabilities to public cloud object storage. This service is specifically designed to create backups of your data volumes, ensuring data protection and recovery options directly in the cloud environment. It automates the backup process and allows for the scheduling and management of backups, making it a vital tool for data retention and compliance strategies.

While Cloud Sync service is focused on synchronizing data between different cloud environments and on-premises systems, it does not specifically cater to backup functionalities. Cloud Tiering is designed to manage data placement efficiently by automatically moving less frequently accessed data to lower-cost storage tiers, which is not related to backing up data. The Cloud Compliance service focuses on ensuring data governance and compliance aspects rather than providing backup solutions. Thus, the Cloud Backup Service is clearly the right choice for backup functionality in this context.
