For non-HA situations, you can do a 2-stage rsync-backup once a day: 1 ) copy all cyrus-folders (/var/spool/cyrus, /var/lib/cyrus etc) via rsync to a backup-folder 2 a) shutdown cyrus 2 b) rsync the same folders to complete the snapshot 2 c) restart cyrus This is a feasible solution with a small downtime (a few seconds), without using murder or lvm-based volumes or something else. If you want, I can send my backup-script for this. -- greetings Roland Am Mittwoch, 16.
