哪位高手用python写过备份脚本

[啥技术也不懂]

你好，哪位高手用python写过备份脚本。可实现对某一目录下的文件进行备份，并自动压缩后，传到指定的别一目录。

改改就可以用

import os
import tarfile

home = '/home/'
backup_dir = '/backup/'

home_dirs = [ name for name in os.listdir(home) if os.path.isdir(os.path.join(home, name)) ]

for directory in home_dirs:
    full_dir = os.path.join(home, directory)
    tar = tarfile.open(os.path.join(backup_dir, directory+'.tar.gz'), 'w:gz')
    tar.add(full_dir)
    tar.close()

引用 1 楼 iasky 的回复:

import os
import tarfile

home = '/home/'
backup_dir = '/backup/'

home_dirs = [ name for name in os.listdir(home) if os.path.isdir(os.path.join(home, name)) ]

for directory in home_dirs:
    full_dir = os.path.join(home, directory)
    tar = tarfile.open(os.path.join(backup_dir, directory+'.tar.gz'), 'w:gz')
    tar.add(full_dir)
    tar.close()

如是查WINDOWS下的 应该怎么写。本人对PYTHON不懂 还希望给段详细加注释的代码 谢谢了！

    'fileList' is a list of file names - full path each name

            a.write(f)
        a.close()
        return True

def dirEntries(dir_name, subdir, *args):
    '''Return a list of file names found in directory 'dir_name'

    Additional arguments, if any, are file extensions to match filenames. Matched
        file names are added to the list.
    If there are no additional arguments, all files found in the directory are
        added to the list.
    Example usage: fileList = dirEntries(r'H:\TEMP', False, 'txt', 'py')
