System information

Components
Barracuda PST Collector Server - The server regulates PST transfers in your network to prevent potential network overload, and
displays the location and status of all PST files (as reported by the Barracuda PST Collector clients). It runs as a Windows service on any
Windows-based computer in your environment, and is controlled by an administrative console from which all PST collection is configured.
Barracuda PST Collector Client - The client locates the PST files on the local system on which it is installed, and sends the PST files to
the Barracuda Message Archiver. The client must be installed on all systems expected to contain PST files that require importing, and
runs as a Windows service. However, it does not have any interface since all configurations are received from the Barracuda PST
Collector Server.
Barracuda Message Archiver - The Barracuda Message Archiver server receives and process the imported PST files, and adds their
contents to the archive.
To create the most comprehensive archive possible, Barracuda Networks recommends that you perform one-time PST collection using the
Barracuda PST Collector to gather and import all historical emails saved in PST files into the Barracuda Message Archiver. Once PST collection
is complete, the Barracuda PST Collector can be safely deactivated and uninstalled.
Configuration & Deployment Options
The following table describes the available configuration and deployment options:
Configuration Option Associated Deployment
Option 1: Administrative template (ADM) with Group Policy (GPO) - r
ecommended
Configure the Barracuda PST Collector Client using the ADM and
deploy using GPO
Option 2 ADM with Custom Deployment:
Configure the Barracuda PST Collector Client using the ADM and
deploy using custom means, e.g., System Center Configuration
Manager (SCCM)
Option 3: Command Line with Custom Deployment Configure the Barracuda PST Collector Client using at the-SERVER
command line, and deploy using custom means, e.g., SCCM
Stages
There are three main stages to PST collection:
Inventory - The Barracuda PST Collector Client scans client systems for PST files, and creates an inventory of those files which is then
submitted to the Barracuda PST Collector Server.
Transfer - The Barracuda PST Collector Server authorizes and schedules each client to send their PST files to the Barracuda Message
Archiver.
Import - The Barracuda Message Archiver receives the PST files directly from the client systems and queues them for automatic import
adding the contents of each PST file into the archive.
All systems running the Barracuda PST Collector Client must have access to both the Barracuda PST Collector Server and the
Barracuda Message Archiver. PST files are collected from the user's hard drives, not network shares or connected devices
such as USB drives. If you want to collect PST files stored on network shares, the Client must be deployed upon the servers
hosting your network shares, and on any external systems from which you want to add content. To import PST files from an
external system (such as a remote user's laptop connected via VPN), or other machines with only intermittent network access,
PST collection happens only when connectivity to the other systems is available. If connectivity is interrupted, the collection
begins anew and does not resume in-place.
Important
All new installations require some initial synchronization tasks to be performed between the Microsoft Exchange Server and the
Barracuda Message Archiver. These tasks, including the direct import of messages, stubbing, and folder synchronization, can take a
fair amount of time to complete. The Barracuda Message Archiver prioritizes these tasks over processing collected PST files.
Therefore, to reduce network traffic as well as potential load on the Barracuda Message Archiver, and to ensure that even the newest
PST files are imported, it is that PST collection begin all such initial integration tasks are complete.highly recommended after
