Hi, @mark2997, i think this solution only get objects that are stored in the root folder. I have to adapt it like this to make it working for the nested folders:

  private
    def get_objects bucket_name, path, root_path=nil
      if root_path.nil?
        root_path = path
      end

      objects = []
      Dir.new(path).each do |pathname|
        next if ['.', '..'].include?(pathname)
        if pathname == SHUCK_METADATA_DIR
          objects << get_object(bucket_name, path[root_path.length..-1], nil)
        else
          objects += get_objects(bucket_name, File.join(path, pathname), root_path)
        end
      end
      return objects
    end
  end

Allactaga - This almost worked for me - I found that it restored the objects with an extra slash at the start of the key (on Linux). There was an out-by-one error and I had to change the following line:

      objects << get_object(bucket_name, path[root_path.length..-1], nil)

to this:

      objects << get_object(bucket_name, path[root_path.length+1..-1], nil)

Hey, I would really like this patch to be included in the master branch! Desperately need the ability to restart the server without loosing all uploaded items on my project....

Why this changes are not merged ?? Or is there any alternate solution to get back all keys after restart
