Prior to making any purchases I called WD and explained my plans and expectations and I was told that it would work.
I purchased a EX4 with the intent of using it as the fileserver for my small office, 3 people with remote access.
I also purchase a mybook 4TB drive that I planned on keeping at home as a remote backup in case of fire or theft
Remote access is not what I expected. I need to be able to access the NAS remotely as a mapped drive. For example I use AutoCAD and when you open a CAD file other multiple drawings called xrefs are opened from saved paths.
Please enable mapping thru mycloud like you do for your cheaper offerings or provide another means.
Also since your last update, backup to usb drive no longer functions.
