Message-Level Backup: Microsoft Exchange and Novell GroupWise
The Barracuda Backup Service connects directly to Microsoft Exchange and Novell GroupWise servers to back up individual emails stored within user mailboxes.
Other File Systems
Mac OS X, Linux/Unix, and Novell Netware systems are backed up using File Share. This method refers to the mechanism that uses standard network protocols, such as CIFS/Samba or SSHFS, to access your servers.
