Technically speaking, you dont need mkdir with xcopy. Xcopy will prompt to create the folder if it's missing or use /i to avoid prompt.

Not sure what you want to achieve by using Mklink. That is a one-time command, used to create a link or a redirect if you like, between two locations (folders in your case), and even tho you can use it in a batch script, there isn't much sense in doing so. The destination folder must exist prior to creating a link, and the data should already be on the destination folder.
The reason MkLink exists is in case you have software that can only work on a specific disk, to be able to make it work on any other disk.
I see that you use the word "Backup" in your path, is that what you want to do? Maybe I'm missing something but I think you need to give more details of what you want to do, otherwise, we can't really help.
