# 1. The files and directories to be backed up are specified in a list.
source = [r\'C:\A\', r\'D:\B\']
# 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 =r\'D:\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))  # 这里原来是这样 "zip -qr \'%s\' %s" % (target, \' \'.join(source))，去掉\'\'就OK了


# Run the backup
if os.system(zip_command) == 0:
    print (\'Successful backup to\', target)
else:
    print (\'Backup FAILED\')\'

 

#这里是windows平台的遇到zip问题

遇到问题：zip不是内部或外部命令，也不是可执行程序。

    分析问题：首先，看自己的电脑是否安装了zip;其次，如果安装了zip，看是否将其所在路径包含进环境变量。

    具体解决步骤：如果你没有安装zip，你可以去该网址内下载相应zip执行文件（http://stahlworks.com/dev/index.php?tool=zipunzip）。
