I have a WD passport ultra that I installed on my computer that has windows 7. I set it for continuous backup , but it does not back up any thing that  I add to my document files. I have to select each document and back it up that way. I uninstalled the software and reinstalled it, but the results are the same. I bought this particular external drive because of the continuous backup option. Not working for me.

Welcome to the Community.

Have you updated WD SmartWare to the latest version? Do you have the same issue when using the scheduled mode?

I completely unistalled all Wd software. Did a reinstall and dia update.It was no help. If I go to scheduled backup and click on the clock the click on backup now nothing happens. Only way I get a back up is if I click on a file and drag it to the passport.
