备份脚本——版本4:

 

#!/usr/bin/env python
# Filename: backup_ver4.py

import os
import time

# 1. The files and directories to be backed up are specified in a list.
source=['D:\\Python\\README.txt']
# If you are using Windows, use source=[r'C:\Documents',r'D:\Work'] or something like that

# 2. The backup must be stored in a main backup directory
target_dir='F:\\' #Remember to change this to what you will be using

# 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
comment=raw_input('Enter a comment --> ')
if len(comment)==0: # check if a comment was entered
	target=today+os.sep+now+'.rar'
else:
	target=today+os.sep+now+'_'+\
	comment.replace(' ','_')+'.rar'

# Create the subdirectory if it isn't already there
if not os.path.exists(today):
	os.mkdir(today) # make directory
	print 'Successfully created directory',today

# 5. We use the zip command (in Unix/Linux) to put the files in a zip archive
rar_command="rar a %s %s" % (target,' '.join(source))

# Run the backup
if os.system(rar_command)==0:
	print 'Successful backup to',target
else:
	print 'Backup FAILED'


 执行:

 

>>> ================================ RESTART ================================
