I bought a 3TB My Book to use solely for backing up my NAS. I was disappointed to learn that the SmartWare application does not support a network drive as a backup source. Nowhere in the description of the item does it mention lack of network drive support as a source.
Please highly consider adding this feature to future versions of SmartWare. I should not be forced to write a script to perform a simple job that your application can easily be updated to perform.
