I have the Thecus N8800, Firmware version 2.01.09 and have experienced major issues with Nsync.

Tech support told me that I should keep folders to 30GB or less when using Nsync. That makes this feature quite impractical. I was trying to sync a folder that was around 300GB but after it "completed" without errors (this took several days), there was nothing in the target folder.

I've also had issues with smaller folders. The sync completes without errors but only some of the files are in the target folder.

Has anyone else had these or other problems with nsync? Any thoughts or suggestions very much appreciated!
