Hello, thanks for the great plugin!
As far as I understood you don't have an option to skip some folders to be uploaded to cloud space. Will be great if you implement such a functionality - for example I would like to store locally all the files placed in the root library folder (MEDIA LIBRARY). Let say this root folder will be used for post featured images, some assets. I am going to create a folder named "Documents" and I would like only the content of that folder to be uploaded (offloaded) to some cloud space (Amazon, Google Drive, etc).
At the moment is there any hook which I could use to skip uploading process to any cloud storage?
