Then use proxy authorization and you'll only need an admin account and
the corresponding password to access every user's mailboxes.

You don't, that's what mx backups are good for. Your secondary mx
the mail to your primary host when it's up. If you want to keep 2 cyrus
perhaps you need a 2-way imapsync solution. And, of course, this only
works for receiving
mails, what about serving your clients and keeping their mails available
at all times ?

See the docs for proxy authorization.
