This is something I haven't sold yet but been looking for a long time. I want my photos available offline next to me on a 2nd drive + online too with mobile access 1:1 (I mean exact 1:1 copy) and instant shareability. Honestly Dropbox would be sooooo perfect, it's exactly what I want but €9.99/month for 2TB is just overkill for me. I'm talking about like 50GBs of stuff maximum. Tried iCloud Drive and Amazon Cloud Drive too but the files didn't end up being exact copies (like either some EXIF data, or the dates have been modified). And iCloud Drive doesn't even allow you to share photos unless you share with iOS people. MS OneDrive felt clunky too me. I really think Dropbox is a great service and wish they were offering something low profile focusing on average people and not... enterprise groups? I'll probably end up paying for Dropbox but I still feel it's an overkill
