Back up to ONE DRIVE?

I just got my 1TB MYPassport and had 500 Gig xferred over and then have it saved on my ONE DRIVE.

It took 2 days, but I believe it is all there. Since I didn’t do it with the BackUp Software that is included (couldn’t change from Drop Box??) Just wondering how I can do an incremental back up on the WD software, or is there another one that I can use?
