How to automatically backup Cisco IOS devices configuration file to a TFTP Server...

We can easily backup our Cisco IOS devices configuration files to a TFTP server whenever we issue the "write memory" command. Now how the make it? Follow the steps below:

#
#config term
(config)#archive
(config-archive)#path tftp://172.16.7.100/switch1-
(config-archive)#write-memory
(config)#exit
#write memory

then you will see the configuration file with file name such as "switch1-Aug-23-15-23-17-0",that is
the prefix you defined previously plus the date and time.

Of course, you can also check the startup-config and find that the configuration is also written into the NVRAM.
