copy(CopySource, Bucket, Key, ExtraArgs=None, Callback=None, SourceClient=None, Config=None)

Copy an object from one S3 location to another.

This is a managed transfer which will perform a multipart copy in multiple threads if necessary.


import boto3
s3 = boto3.resource('s3')
copy_source = {
    'Bucket': 'mybucket',
    'Key': 'mykey'
s3.meta.client.copy(copy_source, 'otherbucket', 'otherkey')
  • CopySource (dict) -- The name of the source bucket, key name of the source object, and optional version ID of the source object. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted.
  • Bucket (str) -- The name of the bucket to copy to
  • Key (str) -- The name of the key to copy to
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the copy.
  • SourceClient (botocore or boto3 Client) -- The client to be used for operation that may happen at the source object. For example, this client is used for the head_object that determines the size of the copy. If no client is provided, the current client is used as the client for the source object.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the copy.
