Feature request: encrypted 1pex

Hello gusifang​! 👋

Welcome to 1Password! If you're using a 1Password account then there is no need to backup your vault since your data is already backed up to your 1Password account in the cloud. If you accidentally delete an item you can always restore it from your 1Password account on 1Password.com: View and restore previous versions of items

Your encrypted data is replicated to redundant copies on our end to guard against any data loss.

Is there a particular reason you’d like to export your items? When you export items, a copy of that data exists outside of 1Password’s protected environment. While your account will still have access to security features like device alerts, two-factor authentication, and more, those protections won’t apply to the exported file.
