NetApp Cloud Backup is the designated service for protecting data residing on Cloud Volumes ONTAP (CVO) systems. It provides an integrated, efficient backup and restore solution by creating block-level, incremental-forever backups of ONTAP volumes and storing them in cost-effective cloud object storage, such as Amazon S3. This service is managed through the NetApp BlueXP console, offering a unified interface for protecting both on-premises and cloud-based ONTAP data. It directly fulfills the requirement for data protection for a CVO for AWS environment.

A. Cloud Sync: This is a data synchronization and migration service used to move data between different storage systems, not a backup solution for point-in-time recovery.

B. Cloud Volumes Service for AWS: This is a separate, fully managed file storage service (NFS/SMB) on AWS, not a data protection tool for Cloud Volumes ONTAP.

D. SaaS Backup: This service is designed to back up and protect data from Software-as-a-Service applications like Microsoft 365 or Salesforce, not ONTAP volumes.
