Copy a Router’s System Image

Backup Your Router.

In some cases, you may want to copy the system image from one device to another, to duplicate settings; or you may want to back it up.

Although the steps for different routers may vary, generally you’ll first want to know the name and size of the system image file. You can do so with the following command:

show flash

The system image is the file with a .bin extension. You should copy down the name of the file so you can enter it if your router prompts you for it.

You can then copy the file with the following command:

copy flash tftp

You’ll then be prompted for the IP address of the TFTP server you’re copying from, the name of the file you’re copying, and the name of the file you’re copying to. Use the names you found from “show flash”; however, you can leave out the “.bin” part.

If you’re trying to replace the system image of another device, use “show flash” to get the name of that device’s system image, and use that name when prompted for the destination file. You’ll then be prompted to confirm that you want to overwrite the system image.

For more information, consult the following instructions for Cisco 2500 Series Routers:
