It's already making me crazy - as a newbie with Mac. I have problem with backup/sync of my pictures. I would like to backup pictures from Photo library (Photo app) to external HDD but more like sync.
- All the new pictures in my Mac should be copied to external HDD.
- Pictures that are already on external HDD should NOT be copied there twice (not classic backup of whole library).
- Pictures I erased from Mac should NOT be erased from external HDD (not classic sync).
- If import of new pictures would be automatic when external HDD is connected it would be great (not manually copying new pictures).
Is that possible with Mac? With Windows I used to do just import new pictures to external HDD library. It never deletes any picture from external HDD even I delete it from my PC library.
