If you do your backups using doveadm backup, then the result should be
consistent, at least in the sense that it would be usable. Your destination can
also be set up similarly with separate storage for indexes.
However I'm pretty sure the consistency would be per mailbox ("folder"), so
e.g. if a user moved a message from one mailbox to another, you could
potentially end up with the message appearing in both mailboxes in the backup.
