Photos Library Clones or Vaults (Time Machine for photos or why aperture is no more?)
one of the best things about aperture was the time machine-like future built in directly into the app, you could create live-updated and maintained clones of your aperture library or as this was named: "Vaults"
is there a similar feature in the new "photos" app?
or am I able to tell Time machine to back up the photos library, which is located on an external drive, to another external drive (not the TM one)?
will a synching app like Synkron keep the library copy functional and serve as a backup maintenance tool?
