You're effectively disabling logging by using these switches.
/NS :: No Size - don't log file sizes.
/NC :: No Class - don't log file classes.
/NFL :: No File List - don't log file names.
/NDL :: No Directory List - don't log directory names.
Remove those and run robocopy from a command prompt. Use /L to have robocopy just list what it intends to do without actually copying any files.
Also remove the /LOG switch and let robocopy write to the console windows. Did you look in the rlogs folder (does it even exist?) at the log.txt file?
Verify the source and destination are what you intend.
