As simple as that. Dirty but does the job: script for remote backup from windows machine to linux using winscp.

C:\Program Files\WinSCP>WinSCP.exe /console /script=lenovo.txt

lenovo.txt consists:

# Automatically answer all prompts negatively not to stall
# the script on errors
option batch on
# Disable overwrite confirmations that conflict with the previous
option confirm off
# Connect using a password
# open user:password@example.com
# Connect
open leming:password@192.168.2.109
# Change remote directory
cd /home/leming/lenovo
# Force binary mode transfer
option transfer binary
# upload my Desktop directory to remote folder
put C:\"Documents and Settings"\leming\Desktop\ /home/leming/lenovo/
# Disconnect
close
# Exit WinSCP
exit
