icloud manual backup

Hello. I am on ios 8.1.3 and I can not figure out how to do a manual backup. I go to settings --> icloud--> Storage--> Manage Storage. I can not find the "Backup Now" button anywhere. Did they get rid of this?? It says my last backup was yesterday but I wanted to do one today because I plan on going to get the iphone 6 today so I wanted a completely up to date backup for when I restore from it on the new phone. Help please? Thanks!
