Backing up and restoring mail data in FortiMail
FortiMail allows you to back up and restore all your existing mail data.
This recipe provides a detailed look at how to configure your FortiMail unit to back up and restore your mail data.
Mail data must be stored locally on the FortiMail hard disk in order for back up to work. If you store your mail data on a NAS device, you cannot back up your data. For more information on selecting storage devices, see "Selecting the mail data storage location" section in the FortiMail Administration Guide.
