python实现备份目录的方法

yipeiwu_com5年前Python基础

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

希望本文所述对大家的Python程序设计有所帮助。
