How to unmount after using mount --bind option?

I have mounted a hard disk /dev/sda1 on /media/backup. Further, I have issued the following command:

mkdir /home/users/Desktop/backup
sudo mount --bind /media/backup /home/users/Desktop/backup

This allows me to access /media/backup from /home/users/Desktop/backup as well. However, now I would like to remove the --bind from /home/users/Desktop/backup. How should I go about doing this correctly?

Do I simply remove the /home/users/Desktop/backup directory? Or should I be using umount?

umount /home/users/Desktop/backup will remove the bind between the 2 folders.

You can then check /home/users/Desktop/backup to make sure that the bind is gone and remove the folder if you wish.
