User Expectations: Transfer Data between Dropbox and S3


Case 1: "Hi, I have a newbie question: is it possible to transfer data from S3 to Dropbox and vice versa, ideally programmatically in Python? It would be great, if possible, to achieve it without the need to download to a local machine and then sync/upload, as the files might be huge. If it is doable, what is the best plan? Does Dropbox Plus work fine? Thank you very much!"
