Cloud Archiving

A cloud-based, indexed archive that allows for granular retention policies, extensive search, role-based auditing/permissions, legal hold, and export. Easy compliance with e-discovery requests and regulatory and policy-retention requirements.

Archiving & Retrieval

Barracuda can archive email messages from any standards-compliant email server or service, including cloud services such as Office 365 and G Suite, as well as email servers such as Exchange, Domino, and GroupWise. SMTP journal forwarding is used to capture an accurate and unmodified copy of each new message at the time it is sent or received, and the Cloud Archiving Service can also retrieve messages directly from email servers using the IMAP or POP3 protocols.

Instant messaging is an increasingly popular form of communication, often used as an alternative to more traditional email messages. Barracuda can archive instant message (IM) conversations, conferences, and other content from both the on-premises and online Office 365 versions of Lync and Skype for Business. IM content is kept in the same secure archive as email data, providing a single solution for organizations to meet their archiving, compliance, and e-discovery requirements.

Data stored in Office 365 and Exchange includes appointments, contacts, tasks, and notes as well as email messages. Barracuda can import these items and manage them in the same way, so they will be retained in accordance with any retention policies that have been defined and can be included in e-discovery searches. They can also be placed on legal hold for as long as necessary, and exported out if needed subsequently.

Barracuda can replicate the folder structure from each individual user’s Exchange or Office 365 mailbox into their archive, making it very easy for them to search and retrieve historical data, and providing a consistent user experience across both current and archived data.

Barracuda provides a multi-function for Microsoft Outlook add‑in that enables users to access and work with all their archived data directly from within their familiar Outlook client. It delivers a fully integrated experience which includes a combined search capability across both mailbox and archived data.

Barracuda Cloud Archiving Service makes it easy for you to export selected data on both an ad‑hoc and a scheduled basis at any time, without incurring additional costs. This capability is available to both administrators and end users, and is managed through the standard web interface. Data can be exported in either PST or EML format.

Compliance, Search & Discovery

Barracuda provides customizable email retention policies, which ensure that an accurate and fully compliant copy of every email sent or received will be retained for the entire period required for that specific data. Retention policies ensure that an accurate and fully compliant copy of every email sent or received will be retained for the entire period required for that specific data. These policies include data in public folders, and can easily be configured to meet the most complex compliance and business needs.

You can designate one or more auditors who can apply legal holds on specific information. Legal hold prevents the data from being tampered with until the hold expires or is removed. Barracuda can apply individual litigation holds to selected data on a case-by-case basis. Each hold will secure the data and prevent it from being amended or deleted for as long as required for each case, regardless of any other retention rules.

Individual messages returned in search results can be tagged for easy identification. These tags can also be included in subsequent search criteria and facilitate activities such as classification and e-discovery.

Barracuda offers easy-to-use search capabilities, ranging from the most basic search by a user for a misplaced email, to advanced Boolean search strategies for audits and e-discovery. Search parameters can be saved and reused, and text searches may include contents, attachments, and a wide range of metadata fields.

Barracuda preserves an accurate record of all system activities, helping you maintain and demonstrate regulatory compliance. The search capability allows administrators to focus in on a specific set of activities, and you can easily export audit data if needed for subsequent analysis or reporting.


Barracuda integrates with LDAP services such as Active Directory and Azure AD to simplify the ongoing management of user-level access controls. Additional users can easily be set up and managed locally if needed, and there is no charge to retain historical data for users who have left.

A variety of predefined user roles are built in, to enable you to easily control individual users’ access to archived data, and to manage their use of specific archiving features and functions. Granular access permissions for auditors can be configured to restrict access to specified sets of data.

Customer data in the Barracuda Cloud is protected using AES 256-bit encryption, with geographically distributed data centers and multiple data copies providing redundancy. SMTP journaling is secured using TLS encryption and public key cryptology (RSA 1024), and remote connections to the Cloud Archiving Service use HTTPS or Secure FTP.
