My Passport stopped backing up

I have a WD 3TB Blue My Passport Portable External Hard Drive - USB 3.0 - WDBYFT0030BBL-WESN. It has stopped backing up. My last backup shows November 7th. It will not even do immediate backups and shows no error messages. Anyone have any experience with this?

Hi Ed_Sanford,

If you are using WD Backup, you can try to check after uninstalling and reinstall of the updated version of WD Backup from WD Support site.

The same thing here, what is up WD?

I installed the new software and the system did one automatic backup. Then, it stopped again and lists the scheduled backup as missed. My computer is a desktop and I never let it go into “sleep” or power down mode. I have 1.2T of free space.
