After a computer has been added, select the data source(s) to be backed up on that computer:

From the 

 page, click Add Data Source next to the associated device from 

which you want to back up. 

On the 

page, select the appropriate data type. 

Continue with the configuration information and save the changes.

Notes for the following data types on authentication and configuring the system to be backed up are 
provided below:

The Barracuda Backup Service uses an SSH (SecureShell) client to access data contained on Mac OS 
X or Linux / Unix based computers running an SSH daemon. The SSH client uses public key 
cryptography to establish a secure connection to the SSH daemon. 

You must configure SSH access to any Mac OS X or Linux / Unix computer you want to back up. 
Follow the on-screen instructions on the 

 page according to the 

operating system.

When you back up a file share you will need to specify the name of the share on the network before 
you can select the folders to be backed up. On a Windows machine, a share name can be a drive 
volume such as "C$”, or a folder and its associated subfolders such as “My Documents”. At a 
minimum you will need Read access to the data that you are backing up and Change Access or 
Full Control to the shares in order to perform a restore. For Mac OS X and Linux / Unix based 
computers with SSH connections the share name should be the entire path to the directory you would 
like to back up, e.g.

 /home/<user>

. 

When you select folders for backup you should begin by selecting the folders at the top of the folder 
tree hierarchy, and then deselect folders lower in the hierarchy that you do not want to back up. You 
can also specify an optional exclusion rule, which is applied when the backup runs, to rule out files 
that don’t meet your back up criteria. Refer to Exclude Files from a Backup (Optional), page 26

 

When you select the Message-Level Backup data type, you must supply the authentication 
information to access your mail server before you can select which mailboxes to back up. In addition 
to the authentication information provided on the Barracuda Backup Service Web interface, you must 
configure the Message-Level settings on your Exchange or GroupWise server.

For Microsoft Exchange servers, refer to “Exchange Message-Level Backups” on the 

 page 

for detailed instructions for configuring message-level backups.

For GroupWise 7 and above, refer to “GroupWise Message-Level Backups” on the 

 page 

for detailed instructions for configuring message-level backups.
