Steps to followBackup Router Configuration to TFTP server and Restore a Configuration
This is a quick guide on how to back up router configurations to TFTP servers and then restore them. This involves copying a router’s configuration to a TFTP Server and back to another router.
You must first ensure that you meet the requirements.
A TFTP server is available on the network to your IP connectivity.
Let’s now move on to how do I backup my router configuration to the TFTP server.
Step 1
When prompted, issue the enable command at the Router> prompt and enter the password.
The prompt changes to Router# which means that the router has entered privileged mode.
Step 2
Copy the running configuration file into the TFTP server
CE_2#copy running-config tftp:
Name or address of remote host []Â 64.104.207.171
Filename of destination [ce_2-confg]Â backup_cfg_for_my_router
You can do it! !
1030 bytes copied within 2.489 seconds (395 bytes/sec).
CE_2#
Step 3
Use a text editor to open the configuration file. Remove any line beginning with “AAA” and search for it.
Notice: This is to disable any security commands that could prevent you from accessing the router.
Step 4
Copy the configuration file from TFTP server to a router in privileged mode (enable). This mode has a basic configuration.
Router#copy TFTP: Running-config
Name or address of remote host []Â 64.104.207.171
Source filename []Â backup_cfg_for_my_router
Destination filename [running-config]?
Accessing tftp://10.66.64.10/backup_cfg_for_my_router…
Loading backup_cfg_for_router from 64.104.207.171 (via FastEthernet0/0): !
[OK – 1030 Bytes]
1030 bytes copied within 9.612 seconds (107 bytes/sec).

Let’s now restore a configuration after we have learned how to backup router configurations to TFTP servers. This is a simple example of how to save the running configuration to TFTP server (10.1.1.1). Every Sunday at 23:00,
Router(config)#kron policy-list Backup
Router(config-kron-policy)#cli show run | redirect
tftp://10.1.1.1/test.cfg
Router(config-kron-policy)#exit
You can!
Router(config.#kron occurrence Backup by 23:00 Sunrecurring
Router(config-kron-occurrence)#policy-list Backup
Then verify. To confirm that the configuration file was copied to the destination router, use the show running-config command.
