Wd discovery vs wd smartware - what happen to the benefits of smartware to discovery?

*Hello, I hope someone can help me with this :innocent: :hourglass: Have had WD Passport Ultra with the WD Smartware Application and did backups great! Where you could choose that it backs up only new files ONLY - I have run out of room on the external hard drive, I purchased a WD Passport Ultra but the software is DISCOVERY - In using that so far I do not see the choices that Smartware App gives you in DISCOVERY, like being able to back up only what has not been backed up yet - Can someone help me with this, I need to have this function, it saves so much time :hourglass: and trying to remember what I already backed up…?

Thank YOU!
