Another intesting thing for this thread: if you set a very high value for mdbox rotate settings, your incremental backups will be awful. If you have hundreds of messages in a mdbox and you doveadm purge one of them, the full .m file must be copied in the incremental / diferential backup.
I use 10 MB+zlib for "main storage" and 250 MB+bzip2 for alternate storage.
