Dev: pyNAT-Backup.v1

Hi there, this script can be used to backup a group of devices automatically at a specific time. If you plan to use inside your organization, you can scale this configuration by reading the IP addresses from a file. As for the credentials, you should be using an encrypted file instead of hard coding the password on your script.

To schedule the task I used Task Scheduler on Windows.

Worth mentioning that this script may have a different behavior if run Linux.

import os

from netmiko import ConnectHandler

from datetime import datetime

import time, subprocess

print("***Backup party is about to start****")

timeLeft = 5

while timeLeft > 0:

    print(timeLeft, end=' \n')

    time.sleep(1)

    timeLeft = timeLeft - 1

# just for fun, I added this to play a song

subprocess.Popen(['start', 'absolute_filepath\filename.mp3'], shell=True)

time.sleep(2)

for ip in range(1, 5):

    router = {

        "host": "192.168.234.3{}".format(ip),

        "username": "silesio",

        "password": "superpassword",

        "device_type": "cisco_ios"

    }

    login_device = ConnectHandler(**router)

    cmd = login_device.send_command("show run")

    get_hostname = login_device.send_command("show run | in hostname")

    get_hostname = get_hostname.split(" ")

    hostname = get_hostname[1]    

    date = datetime.now().strftime("%Y_%m_%d-%I_%M_%S_%p")

    filename = hostname + "_" + date + ".txt"

    with open(filename, 'w') as f:

         f.write(cmd)

    time.sleep(1)

    print(f"\n{hostname}", "Backup completed!")

print("\nok back to work :-)")

time.sleep(2)

To schedule the task to run automatically, set the Trigger and the Action. Use the absolute path to run your code.

And that’s it.
