We probably have a typical tech household setup: multiple phones, several camera's (DSLR, action cameras, drone) and multiple laptops and a desktop. We generate currently 40K photos and 5K videos (around 2TB) per year.<p>Some images are private, only for my wife or for myself, some should be shared. I tried having a 'shared' folder (synced using private OwnCloud), and then manually selecting which photos and videos should be shared. But that is too time consuming and therefor fails.<p>1. What setup do you use to manage and share large amounts of shared photos/videos?<p>2. How do you backup and prevent duplicate data?
