Paperclip multiple storage

I want to move my assets folder to Amazon S3 and since it has a big size, during the transaction i need to upload files both in my local storage and amazon s3 through paperclip.

Is there a way to configure paperclip to store uploaded files both on filesystem and amazon s3?

Maybe you'd benefit from this:

http://airbladesoftware.com/notes/asynchronous-s3/

What you'll have to do is firstly upload to your local storage, and then "asynchronously" upload to S3

This is typically done through the likes of Resque or DelayedJob (as the tutorial demonstrates), and will require you to run some sort of third-party processing engine on your server (typically Redis or similar)

From the tutorial:

### Models ###

class Person < ActiveRecord::Base
  has_attached_file :local_image,
                    path: ":rails_root/public/system/:attachment/:id/:style/:basename.:extension",
                    url:  "/system/:attachment/:id/:style/:basename.:extension"

  has_attached_file :image,
                    styles: {large: '500x500#', medium: '200x200#', small: '70x70#'},
                    convert_options: {all: '-strip'},
                    storage:         :s3,
                    s3_credentials:  "#{Rails.root}/config/s3.yml",
                    s3_permissions:  :private,
                    s3_host_name:    's3-eu-west-1.amazonaws.com',
                    s3_headers:      {'Expires'             => 1.year.from_now.httpdate,
                                      'Content-Disposition' => 'attachment'},
                    path:            "images/:id/:style/:filename"

  after_save :queue_upload_to_s3

  def queue_upload_to_s3
    Delayed::Job.enqueue ImageJob.new(id) if local_image? && local_image_updated_at_changed?
  end

  def upload_to_s3
    self.image = local_image.to_file
    save!
  end
end

class ImageJob < Struct.new(:image_id)
  def perform
    image = Image.find image_id
    image.upload_to_s3
    image.local_image.destroy
  end
end

### Views ###

# app/views/people/edit.html.haml
# ...
= f.file_field :local_image

# app/views/people/show.html.haml
- if @person.image?
  = image_tag @person.image.expiring_url(20, :small)
- else
  = image_tag @person.local_image.url, size: '70x70'
