How to Back Up Your Barracuda Message Archiver
This article refers to the Barracuda Message Archiver release 3.1 or higher, except where noted.
There are two methods for backing up the data partition on your Barracuda Message Archiver from within the web
interface:
Option 1. Configure a Data Partition Mirror – Create a mirror of the Barracuda Message Archiver data partition on an external network
device.
Option 2. Message Store Backup – The data partition of the Barracuda Message Archiver can be accessed by an external backup
solution .such as the Barracuda Backup Server
Option 1. Configure a Data Partition Mirror
You can add additional storage volumes and enable mirroring for existing storage to provide redundancy of data. Configure a real-time mirror of
the Barracuda Message Archiver's data partition through the page.ADVANCED > Storage Manager

Snapshots are performed nightly. Therefore, in the event that data restoration is necessary, typically, the only raw emails that must be
reprocessed are those that arrived in the last day.
Message Archiver models (excluding the 150) provide RAID storage to protect against physical drive
failure. However, other environmental or catastrophic issues may occur that the built-in RAID redundancy
cannot protect against.
For this reason, it is strongly recommended that the Barracuda Message Archiver administrator make use of the available mechanisms
to back up the email data to an external location.
Firmware Release 3.5 and Higher

content by connecting to the Barracuda Message Archiver’s read-only SMB share. Metadata content is available for Mirroring in a future
point release of the firmware.
You must disable anti-virus scan on the external share that is to be used as a mirror before adding the mirror share to the Barracuda
Message Archiver mirror.
You can use any network share that supports the SMB/CIFS file sharing protocols as the mirror. Additionally, the Barracuda Message
