CISCO CONFIG BACKUP

 

                                                        

In this tutorial, I will explain how Kron jobs work on Cisco in

 order to perform an automatic backup of our Cisco equipment.

cisco(config)#kron policy-list backup-conf-trought-tftp-server  

cisco(config-kron-policy)#cli show running-config | redirect tftp://192.168.0.19/lab-alpha-r-cisco-890-confg 

cisco(config-kron-policy)#exit  

cisco(config)#kron occurrence backup-conf-trought-tftp-server at 00:30 Tue recurring 

cisco(config-kron-occurrence)#policy-list backup-conf-trought-tftp-server  

cisco(config-kron-occurrence)#end 

cisco#show clock

cisco#show run

cisco#write

VERIFY

cisco#sh kron schedule

cisco#debug kron all

% create many archive files  marked with time of création and override config file

def add_Kron(ipdev):

    username=''

    passwd=''

    enablepass=''

    cisco_sw = {

        'device_type': 'cisco_ios',

        'host': ipdev,

        'username': username,

        'password': passwd,

        'secret':enablepass,

    }

    swConnect = ConnectHandler(**cisco_sw)

    swConnect.enable()

    swConnect.send_command(enablepass)

    #self.swConnect.send_command('sh int des')

    config_commands = ['conf t', 'kron occurrence backup at 01:00 1 recurring', 'policy-list backup', 'exit', 'kron policy-list backup', 'cli copy running-config tftp://192.168.3.22/'+ipdev,'cli write', 'end', 'wr']

    swConnect.send_config_set(config_commands)

addrs=['15','14','4','10','113','116','19','2','18']

for addr in addrs:

    print('WRITE TO 172.31.31.'+addr)

    add_Kron('172.31.31.'+addr)

R1(config)#archive

R1(config-archive)#log

R1(config-archive)#log ?

  config  Logging changes to the running configuration

R1(config-archive)#log config

R1(config-archive-log-cfg)#?

commands for controlling config logging:

  size        Maximum number of logged commands that will be kept by the config

              log

R1(config-archive-log-cfg)#hidekeys

R1(config-archive-log-cfg)#exit

R1(config-archive)#path tftp://192.168.3.222/$h-

                        

% create many archive files  marked with time of création no override config file

R1(config-archive)#time-period 1 

% Archive within 1 munite

R1(config-archive)#write-memory

% archive when you apply wr cli

R1(config-archive)#do sh archive

The maximum archive configurations allowed is 14.

The next archive file will be named tftp://192.168.3.222/R1--0
