  • Last updated on

To recover the Barracuda CloudGen Firewall, format a USB flash drive and import the CloudGen Firewall ISO image to the drive. You can also include PAR/PCA files and hotfixes. If you are including a PCA file, verify that the password for the PCA file is set to the serial number of your hardware appliance.

If you include hotfixes, they are installed in alphabetical order after the firmware in the post-install section. A reboot is required after hotfix installation.

Before You Begin

Before installing the Barracuda CloudGen Firewall, you must have the following:

  • Create a PAR or PCA file from your current configuration.
  • Empty USB flash drive of at least 2 GB, and no larger than 32 GB.
  • Barracuda Firewall Install application.  
  • CloudGen Firewall ISO image.
  • You must install the Visual C++ Redistributable for Visual Studio 2012 on your computer to use Barracuda F-Series Install.

 Barracuda Firewall Install must have the same major version as the target firmware that should be installed on the USB flash drive.

You can download the Barracuda Firewall Install and ISO image from the Barracuda Networks download portal.
