Whole system backup boot-camp included
I would use winclone to back up the windows separate from the Mac. 


Backing up a Boot Camp partition


The reasons are for file system differences and the simple fact that you have to back up the entire terabyte each time if you just image the drive using disk utility.

But you can also image the whole drive with disk utility - block by block - and have an image of it.  That’s free and included with macOS.
