What backup policy setting allows for shifting infrequently accessed data to cloud storage?

The auto tiering policy is designed specifically to optimize storage costs by moving data between different tiers of storage based on its usage patterns. It allows organizations to automatically transfer infrequently accessed data from high-performance storage to lower-cost cloud storage solutions. This not only reduces costs but also ensures that resources are efficiently allocated.

In an environment with varying access frequencies, this policy intelligently analyzes data access patterns and makes decisions about which data should be transitioned to lower-cost storage resources. This capability is particularly advantageous in cloud environments where storage costs can vary significantly.

In contrast, other backup policies focus more on the immediacy and methods of creating backups rather than the management of data based on access frequency. For instance, synchronous backup typically ensures that data is backed up in real-time or as it is created, while snapshot backup captures a point-in-time image of data for recovery purposes. A data recovery policy, meanwhile, is concerned with how to restore data when required, rather than its tiering and storage management.
