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

$ python backup_ver4.py
