Shut Down a Barracuda Backup Appliance

You can remotely reboot or shut down a Barracuda Backup appliance by logging in to its local web interface. Type the Barracuda Backup IP address in a web browser, log in using your Barracuda Networks account, and go to the System > Device Information page:


You can also perform a safe shutdown of a Barracuda Backup appliance by pressing the POWER button on the front of the device. This issues a shutdown command to all system and service processes before the device powers down.


Do not push the POWER button for more than a couple of seconds. Holding it for five seconds or longer causes an immediate hard shutdown. This interrupts running processes and the Barracuda Backup appliance powers off before unmounting the file system.
