本文介绍了一个使用Python编写的备份脚本，该脚本能够指定要备份的文件和目录，并将其压缩成zip文件存储到指定的备份目录中。脚本支持用户输入备注信息作为zip文件的一部分名称，并通过命令行输出备份状态。

#!/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 = ['"C:\\My Documents"', 'C:\\Code']
# Notice we had to use double quotes inside the string for names with spaces in it.
# 2. The backup must be stored in a main backup directory
target_dir = '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 + os.sep + 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 = 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'
# 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 to put the files in a zip archive
zip_command = "zip -qr {0} {1}".format(target, ' '.join(source))
# Run the backup
if os.system(zip_command) == 0:
print('Successful backup to', target)
else:
print('Backup FAILED')

Output:
$ python backup_ver4.py
Enter a comment --> added new examples
Successful backup to
E:\Backup\20080702\202836_added_new_examples.zip
$ python backup_ver4.py
Enter a comment -->
Successful backup to E:\Backup\20080702\202839.zip
