Update to use AWS::S3 plugin,
user
```ruby
class HerokuS3Backup
  def self.backup
    begin
      include AWS::S3
      puts "[#{Time.now}] heroku:backup started"
      name = "#{ENV['APP_NAME']}-#{Time.now.strftime('%Y-%m-%d-%H%M%S')}.dump"
      s3 = AWS::S3::Base.establish_connection!(
        :access_key_id     => ENV['s3_access_key_id'],
        :secret_access_key => ENV['s3_secret_access_key']
      )
      bucket_name = if ENV['backup_bucket']
        ENV['backup_bucket']
      else
        "#{ENV['APP_NAME']}-heroku-backups"
      end
      bucket = Bucket.find(bucket_name) || Bucket.create(bucket_name)
      
      throw "Amazon bucket error" unless bucket

      S3Object.store("backups/" + name, open("tmp/#{name}"), bucket_name)
      system "rm tmp/#{name}"
      puts "[#{Time.now}] heroku:backup complete"
