Hello Francis,

I also have maildir as mailbox format and use the following script to do 
daily backups

https://github.com/tachtler/dovecot-backup

There's also a more detailed how-to which explains how to do a restore.
But it's only in german language

Google Translate is your friend ;)
perhaps this might help?

greetings
Becki
