I already backup my Zimbra server by using a VM snapshot system. What's the difference between this and ZeXtras Backup?

The main difference between a VM Snapshot manager and ZeXtras Backup is the abstraction layer in which the two system operate: a VM Snapshot manager operates in the lowest layers, meaning that in case of a data loss you will be able to restore the whole server to a previous state, while ZeXtras Backup operates in the Application layer by binding to the mailboxd service of Zimbra, meaning that based on the entity of the data loss you will be able to restore anything from a single item to entire domains.
