System information
Message Import and Copy
All messages imported into a Barracuda Message Archiver in an HA configuration, regardless of the mail source, are copied to the HA peer. New
messages on each system are fully indexed by message content and attachments, and those messages are queued for copy to the other system
in the HA configuration. Because message import takes precedence over message copy to an HA peer, queued copy tasks are deferred until
there is a in new mail import tasks. To view the number of messages waiting to be processed, go to the page and viewpause BASIC > Status

Message Search
Once messages are copied to the HA peer, the messages are available for search on all joined systems. Search results on the HA peer are
limited to the items archived on the system, whether imported from a mail source or pushed from one system to an HA peer.
Offline System in a High Availability Configuration
If a system in the HA configuration goes offline, its mail sources are not imported unless you configure another system to import from those same
sources. The HA peer continues to archive, and messages waiting to be copied to the offline system are deferred and retried indefinitely until the
system is back online.

PST files are transferred between systems, but the messages contained therein are transferred. When a PST file is imported, thenot
Barracuda Message Archiver extracts the messages from the PST file. Those messages are then archived on the primary device and
transferred during the archiving process to the secondary device in the HA configuration.
