 We use [Storage Transfer](https://cloud.google.com/storage-transfer/docs/overview) to automatically transfer the content of the s3 bucket into the Google Object Storage.
 This is a service managed by Google. We'll use it to download the S3 buckets from CloudFront to perform a daily incremental transfer. The transfers only move files that are new, updated, or deleted since the last transfer, minimizing the amount of data that needs to be transferred.
