Enable S3 Lifecycle policies to automatically transition hot data to S3 Standard-IA and cold data to S3 Glacier after 30 days.

Manually move data between storage classes based on access patterns observed in the logs.

Disable versioning to reduce storage costs, as the dataset does not require data protection.

Use S3 Cross-Region Replication to replicate the dataset to another region for disaster recovery purposes, regardless of the access frequency.
