On the Advanced Admin Flash Operations page, I created a tar archive of the current configuration files for my GL.iNet GL-AR750S-Ext Gigabit Travel AC Router using firmware version 3.104. I saved the resulting backup-GL-AR750S-2020-07-02.tar file to my Mac OS Download folder.

Then, on the same Advanced Admin Flash Operations page, I click on ‘choose file’ and select the backup-GL-AR750S-2020-07-02.tar in my Mac OS Download folder.

When I then click on the ‘Upload archive…’ button to restore the configuration files, I am greeted with the message:

“The backup archive does not appear to be a valid gzip file.”

I’m not sure what I need to do to restore the configuration files in my router.

Any thoughts as to what I may be doing incorrectly?

Thanks!
