Using rsync on smb network share

I used pcmanfm-qt to browse to the network share I wanted.
I then did “Copy Path” and got:
smb://rpi3.local/usbhd-ntfs/

I want to rsync a directory on the smb network share.

Do I have to mount it like:
$ sudo mount -t cifs -o user=anonymous //192.168.0.112/usbhd-ntfs /mnt/Slides
