How to install a TFTP server and backup the config file to the TFTP server.
In order to backup your Cisco router running configuration to a TFTP server you will need a TFTP server in place which I’ll tell you how to install and configure it.
1. Download and install a TFTP server, I used a free TFTP server called SolarWinds Free TFTP Server which you can download from here.
2. Install the software on a server that the routers can ping
3. On the TFTP software installed Click File -> Configure and start the TFTP server.
