How can a customer save storage space in Cloud Volumes ONTAP for infrequently accessed data?

The option to enable the data tiering feature and move infrequently accessed data to S3 is the most effective strategy for saving storage space in Cloud Volumes ONTAP for infrequently accessed data.

Data tiering allows organizations to optimize their storage usage by placing less frequently accessed data onto lower-cost storage solutions, such as Amazon S3. By doing this, not only does it free up space in the primary storage environment, but it also reduces costs associated with maintaining frequently accessed storage tiers. Cloud Volumes ONTAP can manage data tiering automatically, ensuring that data is placed on the appropriate storage medium based on its access patterns. This process streamlines storage administration, while maximizing both performance and cost savings.

In contrast, taking AWS snapshots on Amazon EBS storage primarily serves as a backup solution and does not specifically address the challenge of optimizing storage for infrequently accessed data. Similarly, using a third-party data management tool might offer additional functionality, but it could introduce complexity and cost without necessarily providing the integrated tiering benefits of the first option. Lastly, utilizing the NetApp Cloud Sync service to migrate data focuses more on data synchronization and replication rather than data tiering, which is essential for managing infrequently accessed data effectively.
