S3 Object Lock is a StorageGRID feature that enables a compliant information lifecycle management (ILM) policy to prevent object deletion. S3 Object Lock allows you to apply a retention period and a legal hold to individual objects or object versions in buckets with S3 Object Lock enabled. During the retention period, objects cannot be overwritten or deleted unless the legal hold is in effect. If an object is under a legal hold, it cannot be deleted even after the retention period expires. S3 Object Lock helps you to meet regulatory compliance, privacy, and data protection requirements for your object data.

FlexCache allows you to create a cache volume on a Cloud Volumes ONTAP system that is linked to an origin volume on an on-premises system. The cache volume serves the read requests from the cloud analytics application, while the write requests are forwarded to the origin volume.
