Copying Amazon S3 Objects

• Create additional copies of objects
• Rename objects by copying them and deleting the original ones
• Move objects across Amazon S3 locations (e.g., US and EU)
• Update object metadata by copying original objects to new ones that contain new metadata

This example describes how to copy an object using REST.

This example copies the flotsam object from the pacific bucket to the jetsam object of the atlantic bucket, preserving its metadata.
