How do I configure SMB backups for my Barracuda Networks product?

Solution #00002282

All Barracuda Networks products using SMB (Server Message Block) backups, all firmware versions.

  1. It is necessary that the "Share" be shared out at the top/root level and cannot contain spaces or special characters.
  2. Navigate to the Advanced > Backup page of the Barracuda's Web user interface, and select SMB from the drop-down menu.
  3. In the Server Name/IP field, enter the NetBIOS name or IP Address of the server that will be receiving the automated SMB backups.
  4. Then specify the port, which is typically 139 (but may instead be 445).
  5. Next, specify the Username and Password the Barracuda unit should use to log in to the SMB server. This user account must have the proper permissions to write to the shared folder you specify.
note: The syntax on the username can play a big part depending on the OS.. try combinations:
Depending on the SMB version, the Username might need to be formatted in one of these ways: 
  • <username>
  • <SMB domain>/<username> (Windows Server 2000 only) 
  • <username>@<SMB domain> (Windows Server 2003 only)
  • etc...
  1. Specify the shared folder where the Barracuda unit will be placing your automated backup files. Currently, the Barracuda unit is only able to connect to top-level shared folders. This field may need to be preceded by a backslash ( \ ).
  2. Select which settings you would like to back up, and which days and times the backups should be created and stored to your SMB server. 
  3. Specify how many backups you would like to keep at any given time. After this value is met, the Barracuda unit will automatically remove old backups.
