Configuration backup

I've read the section on

https://openwrt.org/docs/guide-user/troubleshooting/backup_restore

But when I make changes to the "wireless" section (such as enable wifi), why is the change not save in the configuration? Is there something more I need to do in sysupgrade.config? by default there is nothing in that file. The only line I added was ths suggested "sysupgrade -l"

I also did a

opkg list-changed-conffiles

And "wireless" never showed up in the list. I guess "wireless" probably not consider as a "Package"?

so then again, when I change configuration thoughout openwrt, how can I make sure I backup ALL the chnages made?

I tried both using the GUI interface to backup and also the command line:

sysupgrade -b /tmp/backup-$(date +%Y-%m-%d).tar.gz

thank you!

Nevermind, I see, there is an option -c in the sysupgrade that will get all the changes to config, I assume it compare from default... not sure..

Although it will be nice if they have a way to get all the changes (only the changes) from the last backup Or be cool if there is someway to get all the change history log.

git with cron can be used to track changes.
