WD My Passport cannot back up all files

Why WD My Passport did not back all my computer files up?

Hello,

What backup software are you using?

This is my problem too! The notification pop up says “Some files failed to back up” There is a “view” button, but that takes me to the “Current backup plan” usual window, and there is no details of which files failed to back up nor how to fix it. I’ve searched but can’t find an answer.
I have a My Passport Ultra, and I’m using whatever software came with it.
I’d love an answer in simple clear language please :slight_smile: Thanks!
