Because the backup settings are not synchronized, to use this feature, you must enable it on both the master and slave units. |
GUI item | Description |
Backup mail data directories | Synchronize system quarantine, email archives, email users’ mailboxes (server mode only), preferences, and per-recipient quarantines. Unless the HA cluster stores its mail data on a NAS server, you should configure the HA cluster to synchronize mail directories. If mail data changes frequently, you can manually initiate a data synchronization when significant changes are complete. For details, see “click HERE to start a configuration/data sync”. |
Backup MTA queue directories | Synchronize the mail queue of the FortiMail unit. For more information on the mail queue, see “Managing the deferred mail queue”. Caution: If the primary unit experiences a hardware failure and you cannot restart it, and if this option is disabled, MTA queue directory data could be lost. Note: Enabling this option can affect the FortiMail unit’s performance, because periodic synchronization of the mail queue can be processor and bandwidth-intensive. Additionally, because the content of the MTA queue directories is very dynamic, periodically synchronizing MTA queue directories between FortiMail units may not guarantee against loss of all email in those directories. Even if MTA queue directory synchronization is disabled, after a failover, a separate synchronization mechanism may successfully prevent loss of MTA queue data. For details, see “Synchronization of MTA queue directories after a failover”. |
