Performing a Recovery Process

Using a PAR File on an USB Thumb Drive

•

Be sure that the unit is powered off.

•

If you have a configuration backup file (PAR file) and wish to restore using this 

configuration, then copy this PAR file to the root directory of the USB thumb 

drive. Name it box.par. Otherwise the unit will be reimaged to default 

configuration.

•

Then, insert the USB stick into one of the USB connectors of the unit and 

switch the appliance on. Depending on the appliance type, it may take a few 

minutes until the recovery process will start.

•

During the recovery process, the status LED of the unit will flash with varying 

intervals.

•

At the end of the recovery process, the status LED’s flashing will be replaced 

by steady green glowing and the unit will beep once.

•

Now, power it off and remove the USB thumb drive.

•

Switch the unit on again. If the system was recovered with a standard 

Barracuda manufactured USB thumb drive (autodetection), the unit will 

subsequently perform another reboot after adjusting some settings.

•

If the system was recovered using an USB thumb drive generated using the 

Barracuda NG Install application specifically for this appliance type, the 

second reboot is not necessary and the unit will directly boot into operation 

mode.

Please see the latest version of the Barracuda NG Firewall Administrator’s Guide delivered with the unit or 

available through http://barracuda.com/doc for an in-depth description of installation and recovery using the unit’s 

built-in Active Recovery Technology.
