Hi,
What are people doing for backups ? My current process is LVM snapshot and backup from that to NFS share. But there seems to be hints around the internet that people use/abuse "doveadm backup" for backup purposes even though it seems its original intention was for transferring mailboxes between dovecot instances. Assuming its ok to "doveadm backup" to an NFS share, is it ok to use "doveadm backup" when dovecot has replication setup (replication-notify etc.) ? Or will it interfere ? Thanks! Laura
This has came up in the past:

I ended up developing my own system based on forwarding all emails to a program (from which I back-up as they come in.)
I am hoping if disaster and/or misfortune were to strike my server, I could simply cat >> back all those files in order (or not come to think of it) in the /var/mail/<username> (or somewhere even better fit in Postfix.)
I am not interested in saving the state of the mailbox as much as all the mails that ever come in (or go out.)
Kindest regards,
Germain
