Would you really "sync" or just "backup"?
To help decide, are you changing messages on both servers or is the
second one just a backup-server?
In case of backup you could use this command:
doveadm backup -u [email protected] ssh backup.server.com doveadm
dsync-server -u [email protected]
the problem is messages can be changed on both servers (this
situation can last for about 1 month till the old server is finally
retired)
I have made initial backup using this command
doveadm -v -o imapc_host=src.srv -o [email protected] -o
[email protected] -o imapc_password='pass' -o
pop3c_password='pass' -o mail_fsync=never -o mail_prefetch_count=20
backup -R -u [email protected] imapc:
Backup was successfull
When i try later to do sync it seems to work only from remote to
loacal (src.srv to the server im runing dovecot sync command on) and
not the other way
if i ommit -R in the sync command dovecot generates an error.
Could this help you?
Cheers!
