```ruby
module BackupRubyHelper
  def application_paths
    applications = node['cloudconductor']['applications']
    dynamic_applications = applications.select { |_, application| application[:type] == 'dynamic' }
    dynamic_applications.keys.map { |name| "archive.add '#{node['rails_part']['app']['base_path']}/#{name}/current'" }.join('\n')
  end
end
```

Use real directory instead of current symbolic link when backup
user
```ruby
module BackupRubyHelper
  def dynamic?
    -> (_, application) { application[:type] == 'dynamic' }
  end

  def application_paths
    applications = node['cloudconductor']['applications']
    paths = applications.select(&dynamic?).keys.map do |name|
      begin
        Pathname.new("#{node['rails_part']['app']['base_path']}/#{name}/current").realpath
      rescue Errno::ENOENT
        nil
      end
    end

    paths.compact.map { |path| "archive.add '#{path}'" }.join("\n")
  end
end
```
