So the reason that doveadm deleted everything yesterday was that I forgot the -R option? "The doveadm backup command forces the destination to look exactly like the source, deleting mails and mailboxes if necessary." Why did doveadm backup create (empty) mailboxes on the new server, when I mistakably used it in the wrong direction? - Had to switch of the email server for over 10 hours yesterday. any messages might not have reached me. is there a mailman archive? _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-leave@dovecot.org Yeah. Backup command, without -R backs to location, not from location. Mailman archive is at https://www.dovecot.org/mailman3/mailman3/lists/ Aki
