With an Amazon Prime subscription one gets unlimited photo storage on Amazon Cloud Drive. While we already have all our photos on OneDrive/Crashplan I am keen on having them also on Amazon Cloud Drive just so we can then see these on Amazon Fire TV.

The Amazon Cloud Drive application for Windows allows you to upload files, but doesn't keep them in sync. Also Amazon has been asking companies to remove the sync feature - Goodsync for example.

Any ideas/suggestions to keep things in sync?
