reparse point

I'm trying to synchronize (local) my local server with my remote server. I can download (backup) the entire remote folder structure without an issue. I then delete the remote folder and recreate the folder and then synchronize (remote) my local server with my remote server. During the upload of the files, in which some are suucessfully uploaded I get:

Any idea what this is, what is causing it, how to resolve?

Thanks for your report.
