如何使用python进行tar备份

Question

我有目录/ home/user1,user2.我想遍历所有用户名home dir,然后生成tar.gz文件,然后将其存储在/ backups目录中.

我是python的新手,所以很困惑如何开始

Answer 1

这应该工作:

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()
