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.
Best regards from Dresden/Germany
Viele Grüße aus Dresden
