# doveadm -o imapc_user=jedi at example.com -o imapc_password=***** backup
-u jedi at example.com -R imapc:/tmp/imapc
dsync(jedi at example.com): Error: Failed to sync mailbox Drafts: STATUS
cannot access mailbox Drafts
dsync(jedi at example.com): Fatal: dsync backup: Looks like you're trying
to run backup in wrong direction. Source is empty and destination is not.
To be clear, I am trying to pull all the mailboxes from the old server
on to this dovecot server, which has no mailboxes populated yet. It
looks like this command would be pushing the messages from here to the
imapc_host rather than pulling?
