Symfony Gaufrette create a copy of an image

I'm using a Symfony Gaufrette for storing images in a filesystem. It works fine when I store an image first time. But I also need to create a copy of the image after it was uploaded to the filesystem. Is there any way to do it?

I use this function for writing:

$filesystem->write($imagepath, file_get_contents($answer->get('imageObject')->getData()));
