You can upload or download files to and from a Cisco WLC by going to Commands > Download File or Upload File. In this case, I needed to backup the Configuration file from WLC to a remote TFTP server.
To upload the Configuration file to a remote server, choose File Type: Configuration > optionally tick Configuration File Encryption > Transfer Mode: TFTP > type the TFTP server IP Address > type the File Path: ./ > type a File Name (BACKUP-1).
WLC will pop-up a warning. Click OK.
The config file transfer completed just within a few seconds.
Here's a snippet of the WLC configuration file.
<OUTPUT TRUNCATED>
transfer upload path ./
transfer upload serverip 172.27.5.17
transfer upload datatype config
transfer upload filename BACKUP-1
# WLC Config End <Tue Feb 20 02:58:02 2018>
