Backing up and restoring system configuration
The ADVANCED > Backup page lets you back up and restore the configuration of your Barracuda Web
Filter. You should back up your system on a regular basis in case you need to restore this information
on a replacement Barracuda Web Filter or in the event your current system data becomes corrupt.
If you are restoring a backup file on a new Barracuda Web Filter that is not configured, you need to
assign your new system an IP address and DNS information on the
BASIC > IP Configuration page
Note the following about the backup file:
• Do not edit backup files. Any configuration changes you want to make need to be done through
the administration interface. The configuration backup file contains a checksum that prevents
the file from being uploaded to the system if any changes are made.
• You can safely view a backup file in Windows WordPad or Microsoft Word. You should avoid
viewing backup files in Windows Notepad because the file can become corrupted if you save the
file from this application.
• The following information is not included in the backup file:
• System password
• System IP information
• DNS information
Updating the Barracuda Web Filter firmware
Use the ADVANCED > Firmware Update page 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 you have the latest firmware version already installed, the Download Now button is disabled.
Note:
Applying a new firmware version results in a temporary loss of service. For this reason, you
should apply new firmware versions during non-business hours.
Updating the spyware, virus, and category definitions
Use the ADVANCED > Energize Updates page to manually update the current spyware, virus, and
category definitions, as well as change the interval at which the Barracuda Web Filter checks for
updates. Energize Updates provide the Barracuda Web Filter with the latest definitions.
