The command copy running-config tftp will not work because you don't have written permission on the TFTP server. The version of 'copy' that comes with IOS uses a proprietary transport layer to get data onto a server. That transport is called TFTP. TFTP is not a reliable nor persistent transport and doesn't require user account credentials.

It seems the OP has the right idea but the wrong command which is the copy tftp running-config command. This command will copy all files in flash to the TFTP server and delete files that are not present on both devices.

Copy running-config startup-config command used only save the changes into switch/router NVRAM

while copy running-config TFTP command is used to create and save this backfile in TFTP server.

Necessary to create a backup is sometimes our important data may be a loss so with help of config we can configure the back which is running on and with help of this command we can restore it!

In some devices "write memory" command does the same.
