Good morning,

We are using Cyrus replication for some years now. It’s just fine. You can play too with
expunge_delayed for avoid removing mail immediately.

  I'm planing to use lvm snaps and rsync for a daily disaster recovery
  backup on my master cyrus (2.4.12 Ubuntu 12.04 LTS):

Have you tested lvm snaps for this purpose yet?  When I tried to use lvm

snapshots in this way a few years ago, it absolutely killed performance


the volume with the active snapshots.  Hopefully things have improved,


I wouldn't bet on it.

Yes, I've tested it and don't see any performance problems while the

snaphot is active. My problem is how to backup about 140 GB mailspool in

an acceptable time slot. What tools are recommended?

If using rsync what options are best practice?

I suggest -aH to preserve single instance storage in the backup.

Just bought some good wine for my weekend project: what about rsnapshot
combined with lvm snapshots (in the pre/postexec scripts of rsnapshot)?
rsnapshot works with rsync and hardlinks. Rotation and some other nice
features come out of the box. Any experiences with cyrus and this tool?
