Bought a new WD Ultra 1 TB portable drive to back up my latop.
Installation went smoothly.
After I click Enable Backup, it did not back up anything even after 1 hour.
There is no indication of progress at all. I have chosen Category Backup and Continuous Backup. The software is WD SmartWare Pro.
When I tried to change to Hourly back and click Backup Now, it shows the error message: The RPC Server is Unavailable(Exception from HRESULT:0x800706BA) Laptop OS is Windows 8.1Pro.
FWIW, I sol.ved my identical failure to start Ultra Backup problem by going to my Windows 7 Control Panel Backup and Restore Icon, and setting up a Backup from my laptop to my external WD My Passport Ultra device. Initial Backup took about 5 hrs.
I don’t know if this will work for your Windows 8 system but its worth a try.
