What should a solutions architect recommend to accomplish this?
Order a Snowball Edge device to copy the data from one Region to another Region.
Transfer contents from the source S3 bucket to a target S3 bucket using the S3 console.
Use the aws S3 sync command to copy data from the source bucket to the destination bucket.
Add a cross-Region replication configuration to copy objects across S3 buckets in different Regions.
Explanations:
AWS Snowball cannot be used for cross-Region data transfer between S3 buckets. Snowball is for transferring large amounts of data to AWS, not for inter-region copying.
Using the S3 console to transfer data is not efficient or scalable for 1 PB of data. It also lacks automation and is not designed for cross-Region operations at this scale.
Theaws s3 synccommand is useful for syncing files, but it is a manual, resource-intensive process and not as efficient as cross-Region replication.
Cross-Region Replication (CRR) is the most efficient and automated solution to copy data between S3 buckets in different Regions. It handles the task seamlessly, ensuring data is replicated across Regions in near real-time.
I conclude that the answer is:
Add a cross-Region replication configuration to copy objects across S3 buckets in different Regions.
