Hi,
I create opt folder to install adguardhome but when I create a backup, I can't see opt folder?
Did you add the path to the backup list?

There is another topic to consider:
- binary/ ABI compatibility, which is not given between sysupgrades (in other words, things will start crashing, if you do it like that)
- and this method is meant for rather small config files only, there is a (devices specific) maximum size limit (depending on RAM- and partition sizes) involved, which is likely to clash badly with something as large as AGH
The smart thing would be not to do it this way.

Ok.
Cause I tried it and after reboot I had /opt but adguardhome did not work, agh from init.d was missing
OpenWRT is different than commercial version firmware.
You are backing up "changes" made to any files that are required to keep your current configuration or even required packages depending on the hardware.
Since OpenWRT is in a constant state of improvement packages can become incompatible and settings within those, changed and can become different CLI if the package was updated and they chose to do so. Use the principle of most important configs for backup and make sure to build your base image with all the required packages to make you device usable if not just as fresh config.
"I find reconfiguring and messing with my network fun and there is always something new in the OpenWRT world to explore."
OpenWRT also has a file manager GUI browser if you are not proficient with CLI in which you can just download the config files you wish to keep. Then you can build a fresh image and swap out the configs after its booted up for the first time.
I would say personally the UASU tool doesn't work for me so I have had to get creative with my backups and restores to reduce downtime since I use OpenWRT as my primary router / firewall / controller. I right now am still using just SNAPSHOTs.
Developers are pretty good about notifying users on what is not compatible with new versions. You can also stick with older images longer with OpenWRT because a lot of times the most important packages are under continual review and development.
The difference in OWRT vs Commercial is you as the owner and system engineer is who will be responsible for your device, not the firmware creator. OpenWRT just gives you the tools to do that. I cant say I feel "safer" on OWRT but the creators are still active here, well some of them, so I would trust them more than a faceless corporation that would squash me if I said they firmware was the case of negative impact. When you know how to build all this yourself, even though you didn't make the packages, you are in control of your own online destiny.

I know that but thanks for the explanations, it is more about AdGuardHome not from open wrt package but from the source, it is more complicated to keep it when sysupgrade...
