Barracuda Message Archiver FAQ
The Barracuda Message Archiver is a dedicated email archiving appliance that captures every inbound, outbound, and internal message and stores it in a tamper-proof, indexed repository. Organizations use it to meet compliance mandates like SEC Rule 17a-4, FINRA, HIPAA, and GDPR, to respond quickly to eDiscovery and legal hold requests, and to offload historical email from primary mail servers.
The physical appliances include built-in storage and ship as rack-mounted or desktop units that operate independently. The Vx models are virtual machine images you deploy on VMware ESXi or Microsoft Hyper-V. Both run the same archiving engine and carry identical feature sets. The Vx series is a good fit if you already have underutilized server capacity or prefer to avoid adding more physical hardware to your environment.
The primary sizing factor is the number of active mailboxes you need to archive. Entry models (150 and 350) handle up to roughly 3,000 mailboxes. Mid-range models (450 and 650) scale to 25,000. Enterprise models (850 through 1050) are built for 50,000 mailboxes and above. Daily message volume and how many years of retention you require also affect how quickly built-in storage fills, so our engineers factor both into a sizing recommendation. Call or email us and we will walk through it with you.
Yes. The Message Archiver supports Microsoft 365, Exchange on-premises, and hybrid environments. It journals messages directly from Exchange or ingests from Microsoft 365 using a Barracuda connector. It also supports Google Workspace for organizations on that platform.
The Message Archiver is commonly deployed to satisfy SEC Rule 17a-4, FINRA, HIPAA, SOX, GDPR, and various state-level data retention requirements. It supports immutable storage, administrator-proof archiving, and full audit trails. Your legal or compliance team should verify that the specific deployment configuration meets your regulatory requirements.
Yes. Barracuda provides migration tools and services to import historical messages from other archive platforms, PST files, and mailbox exports. The migration process preserves original metadata and timestamps so records remain searchable and admissible. Our team can help coordinate the migration scope and sequence so your historical archive is available from day one on the new system.
