Thanks for the responses. What I've done at this point is to use an application called odrive. This allows me to sync the folders of my choice to either my Amazon Cloud or Google Drive. I am syncing my images to Amazon since photo storage is unlimited with the Prime account I maintain. I am syncing my LR catalogs to Google drive since that is free and the catalogs are relatively small at this point - I can't sync these to Amazon since they aren't images, and I would have to pay for that additional storage (i think). Anyway, its too bad there isn't a built in tool from Amazon to do this, but the odrive solution seems simple and the basic application is free, there is a paid version that has some features that might become interesting to me down the road but not just now.
