Bucket / Action / copy


S3.Bucket.copy(CopySource, Key, ExtraArgs=None, Callback=None, SourceClient=None, Config=None)#

Copy an object from one S3 location to an object in this bucket.

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'
bucket = s3.Bucket('otherbucket')
bucket.copy(copy_source, '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.

  • 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.
