python实现备份目录的方法

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
