Moving files without duplicating them to an S3FS-mounted storage bucket

Does the mv command (temporary) duplicate the moved files when the target is an S3FS mount? I have a VM that is reaching total space consumption. So, I'd like to move some files to a storage bucket (**mounted using S3FS**) to free up some space. Since I'm currently using 88.7% of 28.90GB, which is approximately 25.70GB and the directory I plan to move is 8.2GB, I'm afraid to use 100% and get stuck.

-shell
mv /path/sourcefolder/* /path/destinationfolder/
