What Type of Back-up is WD Back up?

Just purchased a My Book 4TB, and started using the WD Backup. I noticed that with the first back up it used almost nearly 1TB. If I schedule a daily back-up, does the program just copy / paste all the files I selected each day? If so I’m going to be out of space on this new drive in a couple of days. OR does it just create an initial full back-up and then only back-up changes? I’ve tried looking all over for this answer.


WD backup will create a initial backup and then just backup changes.

Cool, that’s what I was hoping for and needed. Thank you Hamlet. :smile:
