Cost of copying files between Amazon S3 buckets in different Accounts


I want to copy the S3 files in my account to a different AWS account.

How do I copy without a data transfer fee?

Example command:

aws s3 cp s3://sourceBucket/file s3://targetBucket/

Does it transfer files over the Internet or does AWS transfer over the internal network?

Data size: 71TB

  • If the source and destination buckets are in the same Region, then there is no Data Transfer cost.
