A BYTE OF PYTHON 文件备份的WINRAR版本

教程中的zip文档，不太适合现在win系统中大家安装的winrar软件，

于是我作了一个小更改。。

~~~~~~~~~~

#!/usr/bin/python

# filename: backup_ver1.py

import os

import time

source = ['c:\\device ','c:\\source']

target_dir = 'd:\\backup'

winrar_dir = '"c:\\winrar\\"'

today = target_dir + os.sep + time.strftime('%y_%m_%d')

now = time.strftime('%h_%m_%s')

comment = input('enter a comment --> ')

if len(comment) == 0:

    target = today + os.sep + now + '.zip'

else:

    target = today + os.sep + now + '_' +\

    comment.replace(' ','_') + '.zip'

if not os.path.exists(today):

    os.mkdir(today)

    print('successfully created directory',today)

zip_command = winrar_dir + "winrar.exe a -ad {0} {1}".format(target,''.join(source))

if os.system(zip_command) == 0:

    print('successful backup to' ,target)

    print('backup failed')
