I can't say for certain if this would cause the problem but you aren't defining the path with the remote filename,
notice the / (slash) I added below. In my opinion this should always be defined in the target pathname,
since its not, i don't know what impact it might have.
Code:
0SOH4SOHSTX-SOHSTXhoarderSOHC:\BKP\CWM-BKP_10.rarSOH/CWM-BKP_10.rarSOH419430400
