Backing up the ZCS mailbox server on a regular basis can help you quickly restore your mail service, if an unexpected crash occurs. The backup process writes a consistent snapshot of mailboxes to a designated backup directory.
Figure 2 shows the sequence of a full recovery. When a system is restored, the last full backup is restored, each incremental backup since the last backup is restored, and the archived and current redo logs are restored.
This chapter describes how data is backed up and restored and how to use the CLI tools to backup or restore your ZCS mailbox server. In addition, this chapter also provides information and general guidelines for disaster recovery.
