Backing up the mailbox server on a regular basis can help you quickly restore your email service if there is an unexpected crash. You should include backing up the ZCS server in your system-wide backup process. Only full backups of the ZCS data can be created.
Before backing up the ZCS data, all servers must be stopped. To stop the servers, use the CLI command,
zmcontrol stop. After the backup is complete, to restart the servers, use
zmcontrol start. See Appendix A, for more information about these command.
