The LUCI Backup function for the configuration settings did in 18.06.2 store also the OpenVPN settings in /etc. After upgrading to 18.06.4, the backup function does not do that any more?
Is that intended or an error?
What about other additional applications settings? will they be stored by backup?
Additional items to be backed up are listed in /etc/sysupgrade.conf. You can (and probably have on 18.06.2) edit this file to add your own items to be backed up.
Thanks, that explains it.
I suggest that /etc/sysupgrade.conf should be backed up always!
Sure, the user can do it by referencing itself in /etc/sysupgrade.conf, but it is easy to forget that.
