dsync backup public namespace - how?

Hello,

We just celebrated the launch of our new mailserver setup (Dovecot and Postfix). Really nice!

Now we want to change our quickfix backup with rsync to dsync.

For mailder backup of users this was an easy task:

dsync -v -f -u "${user}" backup "maildir:${destination}" (local file path destination)

We use many public folder with ACL and now we are wondering how we can backup these folder in a similar manner:

a) dsync -u doveadm@domain.com backup -n Namespacename "maildir:/var/vmail-backup/backup/public"

or

b) dsync -v -u doveadm@domain.com -N backup "maildir:${destination}

But this is not working.

a) does nothing, no error b) Error message: doveadm(doveadm@domain.com): Fatal: -N parameter requires syncing with remote host

Any ideas?
