How to Backup Dropbox to Synology NAS?

Hello, I am a Dropbox business user and try to backup my entire Dropbox folder to a Synology NAS. As I understood so far, the official option to do this would be to use the App "Cloud Sync" from Synology. The problem with this option for me is, that i cannot backup all folders in Dropbox.
And the backup would be performed on a regular basis (daily or weekly, no real-time backup is necessary) and paid third-party applications would be also a possibility for me if this won’t be possible with the standard Dropbox or Synology Apps. Would be really thankful for any recommendations.
