How to Backup and Restore Cisco Switch Config File?

Here is the original link from cisco

Use a TFTP Server to Backup and Restore a Configuration

Before you proceed with this method, make sure you have a TFTP server on the network to which you have IP connectivity.

  1. At the Router> prompt, issue the enable command, and provide the required password when prompted.

    The prompt changes to Router#, which indicates that the router is now in privileged mode.

  2. Copy the running configuration file to the TFTP server:
    CE_2#copy running-config tftp:
    Address or name of remote host []? 64.104.207.171
    Destination filename [ce_2-confg]? backup_cfg_for_my_router
    !!
    1030 bytes copied in 2.489 secs (395 bytes/sec)
    CE_2#
  3. Open the configuration file with a text editor. Search for and remove any line that starts with “AAA”.

    Note: This step is to remove any security commands that can lock you out of the router.

  4. Copy the configuration file from the TFTP server to a new router in privileged (enable) mode which has a basic configuration.
    Router#copy tftp: running-config
    Address or name of remote host []? 64.104.207.171
    Source filename []? backup_cfg_for_my_router
    Destination filename [running-config]?
    Accessing tftp://10.66.64.10/backup_cfg_for_my_router...
    Loading backup_cfg_for_router from 64.104.207.171 (via FastEthernet0/0): !
    [OK - 1030 bytes]
