Explanation of File
After completing all prerequisite items, check if the downloaded Backup file has the following files:
1) What to do with “AutoBackupConfig_Windows.py”?
It’s a script that helps you to backup each of your switch running configuration one at a time.
Before running the script, you must manually enter the file path on line 48.
For example, if I need to store the running configurations on a folder called “SW_config” under /usr/user/Desktop/, I should enter “/usr/user/Desktop/SW_config” as my file path.
2) What to do with “device_list.txt”?
This file stores your switch IP, account, and password. Your script will reference this file when performing configuration backup.
For instance, you should see the following two switch’s IP and credential:
Script reads these information line by line.
Each variable should be separated with a comma (,) and do not leave any space.
1. Open terminal
2. Type “ crontab –e”
3. Put the command to Crontab
Cd /home/(user)/Desktop/Zyxel_switch_automation_backup/ && python3 AutoBackupConfig_Ubuntu.py
Well done! You just finish all the steps.
You can adjust your task to next minute to see if it is working properly.
1. This program can only perform one SSH session at a time.
2. User is able to perform hourly backup with “Create Task”.
3. The original script is available in the public domain. Feel free to modify or edit the script for your convenience.
