Backing up and Restoring Your System Configuration
The
ADVANCED > Backup
page lets you back up and restore the configuration of your Barracuda SSL
VPN. You should back up your system on a regular basis in case you need to restore this information
on a replacement Barracuda SSL VPN or in the event your current system data becomes corrupt.
If you are restoring a backup file on a new Barracuda SSL VPN 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 Web 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 Firmware of Your Barracuda SSL VPN
The
ADVANCED
>
Firmware Update
page allows you 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 will be 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-busy hours.
