备份脚本 仅供参考

写了个备份的脚本，使用方法
[user@localhost dir]$ python newbackup.py
Please a target directory:/tmp/mybackup
Already create the dir /tmp/mybackup
Please a source directory:/tmp/newbackup
you have input a directory '/tmp/newbackup'
Please input the file comment:linshi
tar cvf /tmp/mybackup/linshi20110216.tar.gz /tmp/newbackup

2. '''To backup one thing.
   
3.    are you ready'''
   
4. import os,sys,time

10.    target=raw_input("Please a target directory:")
    
11. else:
    
12.    if os.path.exists("%s" %target):

提三点建议：
1·python的运行环境指明，这个脚本应该是python2.x
2·最好能在脚本的前面定义形参，这样按需求修改起来比较方便
3·这种交互的方式是否实用？

    这个脚本只是供自己公司的不太会linux的人备份用的，对于他人实不实用就不知道了，不过我会参考你的建议，非常感谢
