Hi everybody,

I really will love to show my appreciation to all that are part of this forum, thanks for sharing your experiences with others.


Please how can I back up the IOS images and configuration files of my company's routers and switches.

My company uses 2800series, 1800series, 800 series routers and 2960/2950 series switches.


How do I connect the equipments for backup assuming for instance i want to back up to a system (a laptop or to a file folder on a system), thanks.

Tom

Firstly you need a tftp server. If you haven't got one attached is a zip file with one in called tftpd32.exe. It runs on most versions of windows. Just unzip file and then double-click on tftpd32.exe.


Then you need to telnet/ssh onto router and from enable prompt


1) To save the IOS -


router# copy flash tftp


you will be prompted for file from flsah to copy and tftp server IP address.


2) To save config


router# copy run tftp


this will save your running config.

Hi Jon

Thanks for your time and contribution.

Can I back up the ios image and config files of a router that is on production. hope it will not disrupt the operation of our network. i want to be sure of this before i proceed with backing up the ios and config files to the tftp server.


Secondly, one of the cisco 2800 series router we use in one of our branch office suddenly developed a problem, when i accessed it via console, i got message: "flash file cannot be found"

I believe someone tampered with the flash while the router was on production.


we replaced the router with a spare we had.


Is it possible to load the flash file from another cisco 2800 into this malfuntioning cisco 2800?

thanks

Tom

You should be fine doing this on a production router cerainly the config. If the IOS is large and the network busy you may want to do this out of peak hours.


Yes you could either


1) copy IOS from working 2800 to tftp server

copy IOS from tftp server to 2800


OR


2) Set up the working 2800 as a tftp server using the "tftp-server .." command.

Using tftp is UNSECURE. That's why SecureCopy

(aka scp) was invented. Scp is available in

IOS
