python实现备份目录的方法_Python

本文实例讲述了python实现备份目录的方法。分享给大家供大家参考。具体如下：

备份脚本1：

				?

									#!/usr/bin/python

									# Filename: backup_ver1.py

									import os

									import time

									# 1. The files and directories to be backed up are specified in a list.

									source = ['/home/swaroop/byte', '/home/swaroop/bin']

									# 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 = '/mnt/e/backup/' # Remember to change this to what you will be using

									# 3. The files are backed up into a zip file.

									# 4. The name of the zip archive is the current date and time

									target = target_dir + time.strftime('%Y%m%d%H%M%S') + '.zip'

									# 5. We use the zip command (in Unix/Linux) to put the files in a zip archive

									zip_command = "zip -qr '%s' %s" % (target, ' '.join(source))

									# Run the backup

									if os.system(zip_command) == 0:

									  print 'Successful backup to', target

									else:

									  print 'Backup FAILED'

输出：

$ python backup_ver1.py
Successful backup to /mnt/e/backup/20041208073244.zip

备份脚本2：

				?

									#!/usr/bin/python

									# Filename: backup_ver2.py

									import os

									import time

									# 1. The files and directories to be backed up are specified in a list.

									source = ['/home/swaroop/byte', '/home/swaroop/bin']

									# 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 = '/mnt/e/backup/' # 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')

									# 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

									# The name of the zip file

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

									# 5. We use the zip command (in Unix/Linux) to put the files in a zip archive

									zip_command = "zip -qr '%s' %s" % (target, ' '.join(source))

									# Run the backup

									if os.system(zip_command) == 0:

									  print 'Successful backup to', target

									else:

									  print 'Backup FAILED'

输出：

$ python backup_ver2.py
Successfully created directory /mnt/e/backup/20041208
Successful backup to /mnt/e/backup/20041208/080020.zip
$ python backup_ver2.py
Successful backup to /mnt/e/backup/20041208/080428.zip

备份脚本3：

				?

									#!/usr/bin/python

									# Filename: backup_ver4.py

									import os

									import time

									# 1. The files and directories to be backed up are specified in a list.

									source = ['/home/swaroop/byte', '/home/swaroop/bin']

									# 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 = '/mnt/e/backup/' # 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 + '.zip'

									else:

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

									    comment.replace(' ', '_') + '.zip'

									  # Notice the backslash!

									# 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

									zip_command = "zip -qr '%s' %s" % (target, ' '.join(source))

									# Run the backup

									if os.system(zip_command) == 0:

									  print 'Successful backup to', target

									else:

									  print 'Backup FAILED'

输出：

$ python backup_ver4.py
Enter a comment --> added new examples
Successful backup to /mnt/e/backup/20041208/082156_added_new_examples.zip
$ python backup_ver4.py
Enter a comment -->
Successful backup to /mnt/e/backup/20041208/082316.zip
