There are two formats for a copy source:
- For objects not through an access point, the bucket name and object key separated by a forward slash /. For example: mybucket/sales/report.pdf refers to an object sales/report.pdf in the mybucket bucket.
- For objects accessed through an access point, specify the Amazon Resource Name (ARN) in the format arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>.
