What minimum files need to backup to have offline access to them

Hey DefiCzech! 👋

While 1Password stores it's database in C:\Users\%username%\AppData\Local\1Password\data we do not recommend using this as a viable backup as it's only guaranteed to work for the version it originated from. Anytime other database schema changes are made on our end, 1Password will be unable to read this "backup" database without jumping through quite a few conversion hoops among other things to get it back into a useable state.

I recommend giving the thread linked below a look as it's a pretty great overview of how local backups are handled when it comes to folks with memberships, and well worth the read!
