Cost of moving files from a bucket to another one

Hello, Depending on your use case, how much is the data and if the buckets will be in same region or not ( cost for inter-region ) and u should take into consideration cost of service if any ( ex datasync)

Moving data between 2 buckets depends on different factors, such as the amount of data, whether buckets are in the same region, and data transfer involved.

Get familiar with this page: https://aws.amazon.com/s3/pricing/, in particular with the tabs about Data Transfer, Replication and Storage & requests.

For not many objects, CLI or lambda could be enough. For massive size, refer to this. https://repost.aws/knowledge-center/s3-large-transfer-between-buckets

To add more information, these buckets are in the same region and we will need to move about 40TB.

I have checked this, but the information is not clear about my case: https://aws.amazon.com/s3/pricing/

Thank you in advance.
