Last night I tried summat silly on my firewall. It didn't work (for several reasons including ID10T issues)
So I thought I would just restore - I keep a number of backups on the device for just that purpose.
BUT
There seems to be no method, through the GUI, of restoring the backup. Instead I have to SSH to the box and restore via shell.
In fact I restored by uploading a file from my Google Drive - so I don't have an issue here. I was just thinking that it seems odd to have the ability to backup via the GUI, but not be able to restore one of those backups via the GUI
Same place to backup is where a restore can be made. System > Configuration > Backups.
Second section from the top "Restore".
I think you have missed the point.
I cannot restore a config held on the device - there seem to be no mechanism of chosing it. I have to select a backup on my PC
If you log in as root or sudo into root. It's initial shell is a menu. It will let you restore from a backup taken during config changes. You can also put it on a usb, or use sftp to transfer a config over. Then I think just replace the existing config.xml
