Cisco 2811 help

I have a cisco 2811 router and plan to get another for a backup (spare).  I have the config file for the current one and it doesnt seem to be a very large file as we are just allowing communication to pass through to the web.

I am not a cisco guru and tip toe lightly in the area so my question is how do I prepare the alternate 2811 so I can have it ready in the event the orignal goes down?  I can console into the unit and once in can I copy the config and save it off or just tftp the file to the unit and save it?

Thanks for the help

Log in to the existing router and copy the running config to your notepad (or text editor of choice).

Then power up the backup router (not connected to the network) and using the console connection, get into config mode and paste the config.  Then save the running config to startup, power off and you're all set.

When the existing router fails, just disconnect all the cables and connect them to the backup router and power it up.

This assumes that the backup router is identical (IOS version, ports installed, etc.).
