Just a prcision... maybe I misunderstood point
I saw in different posts, that an RSYNC may corrupt the database and cause trouble... therefore, we need a replication system.
I have 2 different servers, running (email server with dovecot) .. Server 1 and Server 2 ( backup system) . if they are running together in parallel, I need a replication in order NOT to corrupt files... correct ? RSYNC MY corrupt files..
now I have only _one system_ ( in fact a VM with sendmail and dovceot ) and I want to backup every 20min, the emails.. normally a simple RSYNC of the email folder should be enough ? even without stopping Dovecot service.. just on the fly ...correct ? ?
Then, in case of crash.. I can reinstall my VM and mount the new NFS folder... that should be OK ?
What do you think ?
Thanks...

Hi,
I am trying using a replication. Here is my config : 10-mail.conf. Before going " on real life " I try to make a very basic example... but without any success :-( bad start
I took the config example on dovecot wiki
The idea is to replicate the user: "user1" on a different server IP 177.28.1.120 at the location /home/SERVER/test and to get at the end the folder "/home/SERVER/test/user1"
On the top, I wish to replication with the user / group : vmail. For the transfer, I use the root login on the backup server to avoid other rights problems at the moment
how to synchronized specific users ? apparently it's trying to sync other things.. :-)
# mbox_very_dirty_syncs = yes mail_plugins=$mail_plugins quota notify replication service replicator { process_min_avail = 1 }
dsync_remote_cmd = ssh -l root 177.28.1.120 doveadm dsync-server -u user1 plugin { mail_replica =remote:root@177.28.1.120:/home/SERVER/test/ }
service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } }
service replicator { unix_listener replicator-doveadm { mode = 0600 user = vmail } }
replication_max_conns = 10
But apparently nothing is happening....
[root@xxx xenia]# doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 24 Waiting 'failed' requests 10 Total number of known users 34and the folder test is empty
Any idea what is wrong ? maybe I should ask a start a cmd line to start the process ? (
