Microsoft Application Support 
The Barracuda Backup Agent provides the ability to back up these Microsoft server applications: 
Exchange, SQL, Hyper-V, System State and Sharepoint. In each case, a full restore of these 
environments allows an organization to recover in the event that their environment has been corrupted 
or destroyed. Additional restore options allow Exchange to be restored to a recovery group or 
database or for Exchange or SQL to be restored to a flat file. The Barracuda Backup Agent also 
provides support for open file backups and file attributes and permissions. 
Email Message-level Backup
The message-level backup of email feature stores every email message from each user mailbox at the 
time of backup. If messages are accidentally deleted or corrupted they can be quickly located and 
restored. Individual email messages, entire folders of emails, or all of the emails for a specific user 
can be restored to the email server without having to restore the entire server. The restored emails can 
be sent directly back to their original location in the user’s mailbox or to an alternate location. You 
can view individual messages that were backed up on a certain date using the Barracuda Backup 
Service Web interface.
Message-level backup of email is not for use in a disaster recovery situation. This feature should be 
used in conjunction with full backups of the email system to provide both convenience and complete 
protection.
Security
There are a number of different security features provided by the Barracuda Backup Service. These 
are described in Securing Your Backups on page 39.
Data Retention Policies
The Barracuda Backup Service provides a configurable and flexible data retention policy based on a 
traditional grandfather-father-son snapshot rotation model. 
Web Interface for Management
The Barracuda Backup Service and the individual Barracuda Backup Servers are managed by an easy-
to-use Web-based interface.
Restore-Focused
The Barracuda Backup Service provides multiple ways to restore your backed-up data. You can 
restore single files, individual email messages and entire systems.
Standard Network Protocols
The Barracuda Backup Service can use standard network protocols like CIFS and SSHFS.
