#filename: backup.py

import os
import time
# source file and direcotry

source = [r'D:\kankan', r'D:\Kugou']

# target file
target_dir = r'C:\backup\\'

#file name and subdirecotry name

today = target_dir + time.strftime('%Y%m%d')

now = time.strftime('%H%M%S')

# create the subdirectory if it isn't exist
if not os.path.exists(today):
    os.mkdir(today)
    print 'successfully created directory'

#name of rar file
target = today + os.sep + now +'.rar'

#rar command

rar_command = r"""C:\Progra~1\WinRAR\Rar.exe a %s %s """%(target,' '.join(source))
print 'rar_command is :',rar_command

if os.system(rar_command)== 0:
    print 'successful open rar'
   
else:
    print 'Failed openrar'
