yes it is off-topic you realized that FS-snapshots/LVM in a virtual machine on a SAN-storage are a another layer you do not want and simply not needed because right done backup-solutions are working without touching the production-server? these days physical hardware in a professional environment is getting more and more exotic because with a additional node in the HA-cluster you counteract the virtualization overhead while the unused power is available for other services and failover so the replication slave makes LVM/Snapshots on the production machine obsolete and gives you much more flexibility while the whole environment gives you much better snapshot/backup options like backup the whole server as it is consistently for disaster recovery the mailserver itself is only a small puzzle
