Trying to make the best backups -opkg extras examples?

I am trying to make the best backup (configs and packages) for simple restoring. I am trying to work on tailscale subnet issues.
Routinely, I will have to reset the router.

So I reset the router. Now I have scp the JMPOED file to the router.

Do I opkg import /path/x.jpoed?
Is it opkg restore after that?

I have read the wiki but I do not understand the usage as it relates to the order in this use case.

And do I do the packages first and then the backup configuration second?

If there is a better/easier method please let me know. System flash configuration?

Thank you for your help.
