How do I do an S3 copy between regions using aws cli?

Question

It was far to difficult to figure this out. It wasn't obvious to me and lots of explanations left out key details. I will answer this with the solution. Sorry if it seems obvious to you, but given how many searches and experiments it took me to do this, I think it is quite worthwhile to show others how to do it.

Answer 1

Explicitly show both the source and the destination regions.

$ aws s3 cp s3://my-source-bucket-in-us-west-2/ \

      s3://my-target-bucket-in-us-east-1/ \

      --recursive --source-region us-west-2 --region us-east-1

Or on Windows

> aws s3 cp s3://my-source-bucket-in-us-west-2/ ^

          s3://my-target-bucket-in-us-east-1/ ^

          --recursive --source-region us-west-2 --region us-east-1
