Well for the purpose of upgrading your server, you could do the following:
- Rsync your maildir directories to a backup directory
- repeat rsync again so most of your changed files have been synced
- shut down your dovecot and smtp servers
- rsync one more time - should be relatively fast
- restart your dovecot and smtp servers
Otherwise, just schedule downtime and use whatever backup method you prefer. You will probably want to backup and then leave dovecot and smtp server down until you've completed the dovecot upgrade anyway, so you may as well schedule downtime for the entire process and do the dovecot upgrade between steps 4 and 5 above.

I'd say the correct term is not broken but missing. backup was implemented in later version.
With maildir keeping a copy of the content is sufficient backup.

Ok, so for lack of any other information, am I to conclude that the doveadm backup command is broken in 2.0.9? I have been through the wiki for it back and forth and cannot make it work.
Yes, I need to upgrade, there is no question, but I won’t do that without a maildir backup. I would prefer to use the built-in dovecot mechanisms for that than something else.
