Hi, I'm doing a backup from a Cyrus to a Dovecot (2.2.24) instance. On the dovecot side (localhost) I'm running doveadm \ -o mail_plugins= \ -o imapc_master_user=cyrus \ -o imapc_password=<cyrus-passwd> \ -o imapc_host=<cyrus-ip> \ \ -o imapc_ssl_verify=no \ -o imapc_ssl=imaps \ -o imapc_port=993 \ backup -f -u "heiko" -R imapc: dsync(heiko): Warning: Deleting mailbox 'Trash': UID=18290 already exists locally for a different mail: highest than remote's UIDs (remote UIDNEXT=19588) The destination (local system) does not change while running backup, the remote system (cyrus) can't be stopped while running this backup. Repeating the above command sometimes helps, sometimes not. Sometimes the names of the mailboxes dsync deletes change? Any idea how to stabilize it? I'm talking about cca 4500 mailboxes.
