Summary about the backup system

I just finished a small part of the backup system. I should pay more attention to the designs...

The part I have finished

1. Extract the file list I need to backup and write them to a file. This is in fact the walk on the given directory.

2. Compare this filelist with the previous one, and identify the changes (updates, removal and newly-added). Copy these changes to the directory named with the current date, and write them to the change-logs.

The Part I need to work on tomorrow:

1. Copy these files to the stdsun, zip them if needed.

2. Write the recovery code for the files based on the logs.
This program is complex.


Tomorrow I need to learn the debugging of Python first, and write something about the research.
