How to sync Yosemite Photos library to Synology Diskstation?

I'd like to know if anyone has found a way to sync the new Photos app on Yosemite with a Synology diskstation. I know backing up is easily done either using Time Machine or another app, but I want to sync the 'Events' of Photos to my Diskstation to allow for it to index the files to the built in Photo Station application on the NAS.
