Consists of the following values:

  • A description

  • An Amazon S3 location for the destination of the file copy.

  • A flag that indicates whether to overwrite an existing file of the same name. The default is FALSE.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{
  "DestinationFileLocation" : S3FileLocation,
  "Name" : String,
  "OverwriteExisting" : String,
  "SourceFileLocation" : String
}

Properties

DestinationFileLocation

Specifies the location for the file being copied. Use ${Transfer:UserName} or ${Transfer:UploadDate} in this field to parametrize the destination prefix by username or uploaded date.

  • Set the value of DestinationFileLocation to ${Transfer:UserName} to copy uploaded files to an Amazon S3 bucket that is prefixed with the name of the Transfer Family user that uploaded the file.

  • Set the value of DestinationFileLocation to ${Transfer:UploadDate} to copy uploaded files to an Amazon S3 bucket that is prefixed with the date of the upload.

    Note

    The system resolves UploadDate to a date format of YYYY-MM-DD, based on the date the file is uploaded in UTC.
