改进版：多线程并行备份：

import threading
import paramiko
from time import sleep, ctime


ips = ["10.20.1.240", "172.16.100.2", "172.16.101.2"]
user = "用户名"
passwd = "密码"


def dell_tftp(ip):
    client = paramiko.SSHClient()

    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(ip, 22, username=user, password=passwd)
    remote_connection = client.invoke_shell()
    # output = remote_connection.recv(1000)
    # sleep(1)
    # print(output)

    sleep(1)
    remote_connection.send("enable\n")
    # output1 = remote_connection.recv(5000)
    # print(output1)

    sleep(1)
    remote_connection.send("enable密码\n")
    # output2 = remote_connection.recv(5000)
    # print(output2)

    sleep(1)
    remote_connection.send(
        "copy startup-config tftp://10.20.0.201/dell-%s.txt\n" %
        ip)
    # output3 = remote_connection.recv(5000)
    sleep(2)
    # print(output3)


def main():
    print('starting at:', ctime())
    threads = []
    nloops = range(len(ips))

    for i in nloops:
        t = threading.Thread(target=dell_tftp, args=(ips[i],))
        threads.append(t)

    for i in nloops:
        threads[i].start()

    for t in threads:
        t.join()

    print('all DONE at:', ctime())

if __name__ == '__main__':
    main()
