Thanks for writing back! .1pex, which sounds like a safe variant of .1PIF as well as somewhat reminiscent of the old "export to HTML" functionality, definitely counts as a win, caveats notwithstanding. While not ideal from a UX standpoint, I'm wondering whether there is a way to use Automator or a script or daemon of some sort to create backups on a scheduled basis. 1Password does have a CLI, yes?
P.S. The post at your link frankly rankles given the decision to partially break local vaults in 1Password 7.8 for iOS and iPadOS. But that's a discussion for another thread.
