Backup and Restoring the Cisco IOS--
I want to save my configuration of router in a TFTP server so in case of any failure like RAM is corrupted and we need to change or some time we need to change router also.So in this case we don't need to configure new router again we can use our saved configuration.
1.Backup--
First we will take backup of our router configuration.
Router# show version
After apply this command you'll see a large message in that message try to find
"System returned to ROM by power-on
System image file is "c2800nm-advipservicesk9-mz.124-15.T1.bin""
This is image of router IOS . Now copy the image file (as highlighted text ).
Router#copy flash: tftp:
Source filename []? c2800nm-advipservicesk9-mz.124-15.T1.bin
Address or name of remote host []? 192.168.2.2
Destination filename [c2800nm-advipservicesk9-mz.124-15.T1.bin]?
