为重要的文件进行备份:
思路：
1.需要备份的文件和目录由一个列表指定。
2.备份应该保存在主备份目录中。
3.文件备份成一个tar.gz文件。
4.zip存档的名称是当前的日期和时间。
5.我们使用标准的tar.gz命令.
#!/usr/bin/env python
#coding=utf-8
#filename: backup_ver2.py
import os
import time
#1. 备份文件的列表
source = ['/home/medees/Pictures/', '/home/medees/script/']
#If you are using Windows,use source = [r'C:\Documents', r'D:\Work'] or something like that
#2. 备份文件存放的主目录
target_dir = '/home/medees/backup/' #Remember to change this to what you will be using
#3. The files are backed up into a zip file
#4. 主备份目录下的当天日期
today = target_dir + time.strftime('%Y%m%d')
# 压缩的当前时间
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 + '.tar.gz'
else:
target = today + os.sep + now + '_' + \
comment.replace(' ', '_') + '.tar.gz'
#如果当天日期的目录不存在则创建
if not os.path.exists(today):
os.mkdir(today)
print 'Successfully created directory', today
#5. We use the zip command (in Unix/Linux) to put the files in a zip archiv
#zip_command = "zip -qr '%s' %s" % (target, ' '.join(source))
tar_command = "tar -cvzf %s %s" % (target, ' '.join(source))
#Run the backup
if os.system(tar_command) == 0:
print 'Successful backup to', target
else:
print 'Backup FAILED'
