Syncing to Amazon Cloud storage

<p>Recently I've started using the unlimited storage for photos i have available (via amazon prime) on the amazon cloud drive, using this as a backup to what is on my HDD. Unfortunately, there is no option to automatically sync specified folders - either you have to manually upload individual folders or pictures or you have to delete the old folder and replace in its entirety. Neither is a good approach to doing something you want to do regularly. I'm wondering if anyone is using any of the 3rd party synchronization tools that seem to offer solutions to this problem. A couple I've seen are odrive and GoodSync, I'm sure there are others. What is your experience?</p>

<p>That's a good question, Chris. I've used the Amazon Music Uploader but I'd be serious to see if they come out with a similar program for photos.<br>

Also- do you know if the files are compressed or not? I can't find a clear answer about this anywhere. </p>
