Has anyone successfully setup backup and restore using the snapshot feature of the storage layer? This is briefly mentioned in the admin guide but no setup examples are provided. Currently running Zimbra in a Xen VM+LVM and would like to take advantage of the functionality.
From the admin guide...
Using snapshots to backup and restore
You can also backup and restore your server using the snapshot feature provided by the storage layer, rather than using Zimbra’s backup and restore feature. Using snapshots, you can maintain a standby site to use if your primary site fails at some point of time and reroute users to the standby site to keep operations running.
