I have the same error when using a usb 3.0 disk as safe point. Formating the USB disk to ntfs or FAT32 do not solve the problem. It looks like the backup are almost finished (take several hours) . My 4tb wdmycloud has the latest firmware.
I know I’m a little late to the party on this but I’m having the same issue of not being able to create a safepoint. Just wondering if a solution was found?
I have a 4TB WD Elements external drive connected to the 2TB Mycloud with the lattest firmwar
Is there anything specific/formating wise that I need to do for the Elements drive?
I was hoping to use the Elements drive to backup the Mycloud using safepoint and backup a 500G laptop and 250G netbook using Windows backup.
