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
