Indeed, doveadm sync would have to be ran at some certain interval in order to ensure you have all the messages. Typically when converting a mailbox or transferring accounts across servers, we run it up to a max of 7 times till no new messages come in due to sync so that we can be sure we "got everything" including messages that came in while we were doing the sync.
If it's just a question of cloning your mailbox locally/on another server, putting doveadm sync on a cron should suffice to do what is desired here. That said, doveadm sync will not delete the messages once done, so you'd need to also handle that yourself. If the main concern is dodging quota full, I'd probably just use POP3 to connect (if they offer it) instead, as almost every POP3 server I know of deletes all the remote messages after fetch, thus ensuring your quota'd mailbox is never much of a problem except between the interval your mail client checks for new mail.

I just know of the tool and not how to use it. It doesn't look like it supports continually running it in the background, but you can always put it in a loop in a shell script, perhaps with a delay between iterations. If you use cron, you have to be careful that it is not already running when it gets fires again.
