Sync albums with a NAS Synology

Hi everybody,

I'm looking for a solution regarding my albums in the Photos app of my Mac. In fact, I recently bought a Mac and I've migrated all my photos on the official app of Apple. I love it and I want to keep it due to the fact that I can have all my photos synchronized on all my devices.

However, I have a problem that I can't resolve for the moment. In fact, I have a NAS Synology in which one I have all my photos and videos sorted thanks to the Synology app. I really need to keep this because it's by this way that I can view my photos and videos on my TV (via DLNA or via the official Synology app on the SmartTV).

Therefore, is there a way to synchronize all my Photos Library from my Mac to my Synology NAS with a folders structure (one-way direction, so I'll never modify the photos on the NAS, but if I remove a photo from the MAC, this should be replicated on my NAS)?

I found some solutions via some scripts, but all of them allow only a backup of the albums with no sync possibilities. If a photo is removed from an album or if photos are re-organized, it's not taken into account.

The best application I found is "Photos To Disk" (http://www.photos-to-disk.com/index.html) but this is not automatic, and there is no syncing option...

Is someone able to provide me with a solution?

Thank you very much for your help.

Best regards,

Damien
