This will guide you through how to configure your Cisco switches to save and backup their configuration automatically. The backup occurs at 8pm every day and every time the running configuration is saved.

Setup a TFTP server

You will need to setup a TFTP server if you don't already have one. I use TFTP32 and install it as a service so it automatically launches when the server is booted.

Ensure your switch time is correctly set.

To ensure your switch is performing the backup to the correct schedule you need to ensure the time is correct on the switch.
