The Barracuda Message Archiver is a complete email archiving solution designed for optimizing email storage, meeting regulatory compliance and e-discovery requirements, and seamless end-user integration with Outlook to search all of your existing email. The Barracuda Email Security Gateway securely encrypts email which is then sent via Transport Layer Security (TLS) to the cloud-based Message Center ensuring email is encrypted and keys are securely stored using AES 256-bit encryption. Organizations using a Barracuda Email Security Gateway and Email Encryption Service can include a Barracuda Message Archiver to capture all encrypted inbound and outbound messages. You can encrypt and archive journaled email by partnering the Barracuda Email Security Gateway and the Barracuda Message Archiver. Data stored in PST files may be relevant to ongoing e-discovery or data disclosure exercises, but it can be problematic to identify, retrieve, and search this data because the location of all files may not be known, or they may not be easily accessible to IT administrators or auditors.This article applies to the Barracuda Message Archiver firmware version 5.0 and higher, and the Barracuda Email Security Gateway.However, due to their dispersed location and the difficulty of tracking numbers and locations, they are often excluded from this process, creating a significant ongoing risk to the organization. Data stored in PST files should be managed in accordance with your regulatory compliance and data retention policies.They are typically stored on end-user laptops or desktops, and not backed up on a regular basis, therefore there is a high risk that they be lost or misplaced.Due to their size, they are also susceptible to internal corruption if they are located on a network share or accessed over a network, and Microsoft specifically advises against this. They are notoriously unreliable, as they are not designed to hold large amounts of email data, and 10 to 15 percent of an IT department’s daily helpdesk calls can be taken up with looking after these files.They can be password-protected, but in practice this provides ineffective protection. They are a security risk, as they can easily be disconnected from Outlook and copied or moved to another Outlook client.However, the use of PST files is no longer recommended: It generates PST files to store email locally for each user. The AutoArchive function in Outlook allows users to bypass the mailbox quota limits, and was turned on by default in Outlook 20. Backup solutions typically do not provide direct access for end users to search and retrieve historical data, or allow them to restore individual items without involving IT.įor these reasons we recommend the use of a dedicated archiving solution to ensure effective data protection and preservation.The point‑in‑time revisions stored by backup solutions contain multiple versions of data items, which must be reconciled to produce a single set of accurate and verifiable results for e-discovery.Backups do not provide full‑text and multi‑level search, tagging, and export capabilities, which are may be critical for compliance with e-discovery requests. Retention policies within backups do not provide the granular level of control over data retention needed to meet more complex compliance requirements.Backups capture data at specific points in time, so cannot ensure a 100-percent complete and accurate record of all data.There are significant limitations and deficiencies with this approach which make it inadvisable.
