Backing up and Restoring Your System Configuration
Back up and restore the configuration of your Barracuda Link Balancer using the Advanced > Backup 
page. You should back up your system on a regular basis in case you need to restore this information 
on a replacement Barracuda Link Balancer or in the event the current system data becomes corrupt.
If you are restoring a backup file on a new Barracuda Link Balancer that is not configured, first enter 
the new system’s IP address and DNS information on the 
Basic > IP Configuration page.
The following information is not included in the backup file:
• System password
• System IP information
•DNS information
Updating the Firmware of Your Barracuda Link Balancer
The Advanced > Firmware Update page allows you to manually update the firmware version of the 
system or revert to a previous version. The only time you should revert back to an old firmware 
version is if you recently downloaded a new version that is causing unexpected problems. In this case, 
call Barracuda Networks Technical Support before reverting back to a previous firmware version.
If there is a more recent firmware version available than what is already installed, the 
Download Now 
button will be enabled.
Applying a new firmware version will result in a short service outage.
Replacing a Failed System
Before you replace your Barracuda Link Balancer, use the tools provided on the Advanced > 
Troubleshooting page to try to resolve the problem.
