To me, it's not that complicated. The point of a vault backup is to not leave you completely hosed, even if it means some new entries didn't make it in. You don't really need to automate anything, set a calendar reminder every few months if you're prone to forgetting and login to do an export.

Automating this definitely seems like a bad idea, but it depends on where you're putting the backup. I put mine into encrypted, offline storage and thats not something I want to keep connected all the time for a cron job. That, and you're dealing more moving pieces (CLI with vulns like you mentioned) and automating access to your vault.

I disagree because life is more complicated than just your password manager, so you are not just adding a reminder to backup your vault, it's another thing you need to remember. That might work for you, and it's ok, for me it's a liability.
