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).

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).
Adding the T option did not copy new, nor modified files. Nothing was listed in the log. First it said the file I modified was skipped, then it said that it and the new file were both skipped. Using DAT (the default) also did nothing. Using /Copyall (DATSOU) said that I "do not have the Manage Autiting user right". DATS gave same error as before.
I will look into the native backup options (can snapshots be excluded?), or revise my VB6 program and run it on the W10 box.

Thank you. I used the "d" option, did not see the "t" from the PC for a small folder successully. Then set up a backup job of the entire 5.44TB (usable) 4.70 (free), and to the WDC 4TB over the USB 3.0 rear port, it took 11 hours! Seems excessively long.
However, my question, (and RTM might be the answer) is how do I exclude certain files/folders? The Mac leaves a lot of ".DS*" and "._*" files around, and heaven forbid the drive gets a Recycle Bin (although I think I kind of liked that on the older ReadyNAS devices vs snapshot, just scared of editing the files and "bricking" it.)
Thanks and have a happy season.

There are several ways to exclude (and include) with Robocopy. For your specific patterns, this is what you'd want:
/XF *.DS /XF *._*
There's a good command line summary here: http://ss64.com/nt/robocopy.html (it includes a bit more explanation than Microsoft's page here: https://technet.microsoft.com/en-us/library/cc733145.aspx )
