Files not backing up from my computer to passport

When I first installed the passport drive it backed up but does not seem to have backed up my files since July.

Hello, welcome to the community.

Which software are you using to backup the computer? Are you backing up to the drive while connected wireless or wired?

I am using wd smartware. I floated it and was able to backup my pc. Now I’m backing up my laptop. I have it set to continuously back up but I don’t know how to tell if that’s happening. Thanks for responding.
