ReadyNAS 314 USB failures with Robocopy
I am using ROBOCOPY to backup data to a 4TB WDC hard drive via an OWC USB 3.0 enclosure connected to one of the rear ports. The command is robocopy m: s:\aatest /e /R:1 /MIN:1 /TS /NP /FP /NDL /X...

The idea on /copy:dt was to explicitly exclude the attribute copy. The forum firmware turned the :d into an emoticon (an annoying habit it has).

I copy successfully when hooked up directly to the PC. It just seemed that the USB port on the rear was a good thing. Am I wrong?
If you are driving the backup from the PC, it is better to use a direcly connected USB drive. Otherwise you are transfering all the data over the network twice.

Try adding /COPY:DT to your command line.
However, this is a very inefficient way to copy (the data goes from the NAS to the PC, and then back to the NAS USB drive).
Two faster methods:
(a) attach the WDC disk directly to the PC (so the data only transits the network once).
(b) use an RN314 backup job (so the data doesn't transit the network at all).
