Continue above. After the password-free login above, this article simply makes a regular log backup and integrates the logs on other machines locally. The logic is relatively simple and can be modified as needed. The final effect is to organize the files of several machines into a compressed package and save it locally every day, and delete the backup one year ago. I won’t go into details here, just look at the code directly.
