[python]备份文件的一个小Demo
前些日子，看了一下python，修改了一个小例子共享下，（整体代码是从网上复制下来的，但是运行的时候，总是会报错，增加了rar命令的路径和rar 的命令，使该问题得到了解决）大神勿喷：说明：Windows环境下将D盘的documents\python目录被分到F盘python\backup文件夹下：#-*-coding:UTF-8 -*-

# Filename: backup_ver4.py
import os
import time
# 1.需要备份的文件目录
source = ['D:\\documents\\python']
# 2. 备份文件到目标路径
target_dir = 'F:\\python\\backup\\'
# 3. The files are backed up into a zip file.
# 4. The current day is the name of the subdirectory in the main directory
today = target_dir + time.strftime('%Y%m%d')
# The current time is the name of the zip archive
now = time.strftime('%H%M%S')
# Take a comment from the user to create the name of the zip file

print target
# Create the subdirectory if it isn't already there
if not os.path.exists(today):
print 'running in mkdir'
os.mkdir(today)# make directory
print('Successfully created directory', today)
# 5. 用winrar的rar命令压缩文件，但首先要安装有winrar且设置winrar到环境变量的路径path中
print 'the two strings are %s and %s'%(target,''.join(source))
#这里需要添加rar的绝对路径，即使配置了环境，还是无法执行rar命令
zip_command = '"C:\\Program Files\\WinRAR\\rar.exe" a -r %s %s' %(target,''.join(source))
print zip_command
if os.system(zip_command)==0:
print('Successful backup to', target)
else:
print('Backup FAILED')
print 'this program ended'
随手memo一下，以后备查，好习惯{:10_455:} 赞一个！好东西哈哈哈
