To back up and restore configurations for the Barracuda CloudGen Firewall or the Barracuda Firewall Control Center, a Portable Archive (PAR) file containing all configuration settings is used.
The following items are backed up in PAR files:
- Configuration data
- CC global admin accounts (only on CC)
- X.509 certificates from the CC PKI (only on CC)
- Revision Control System data (only on CC)
The following items are NOT backed up and must be backed up separately:
- Log files of the Barracuda CloudGen Firewall and Control Center (CC)
- Statistics data
- Eventing database
- Spamfilter learning database
- Mail gateway queue data
For information on how to back up and restore the Barracuda CloudGen Firewall, see: How to Back Up and Restore Firewall and Control Center Configurations.

Recover the CloudGen Firewall Using a USB Flash Drive
You can also use a USB flash drive to recover your Barracuda CloudGen Firewall. Import the CloudGen Firewall ISO image, PAR/PCA files, and hotfixes to the drive and install them on the appliance.

Restore the Firewall Configuration when Replacing Hardware Firewall Models
When a CloudGen Firewall gets replaced with a newer hardware revision model of the same model (e.g., from F400 Rev. A to F400 Rev. B.), you can restore the configuration on the new appliance using a configuration backup (PAR file) of the previous configuration. This procedure can also be used when cold spare firewalls are used as replacements.
For more information, see How to Restore a Configuration on Standalone Appliances After an RMA.
Using Active Recovery Technology (ART)
Active Recovery Technology (ART) recovers your CloudGen Firewall from the command-line interface using a serial console or SSH. The ART menu allows administrators to reinstall the CloudGen Firewall and perform minor configuration changes. The ART menu is entered either by pressing a key when prompted while the system boots up or if selected when rebooting the firewall via Barracuda Firewall Admin.
For more information, see How to Use Active Recovery Technology (ART).
