Microsoft Azure provides the “Capture” option to capture the state of a running Barracuda Web Application Firewall. It captures the state of the system and creates a template that can be used to deploy similar instance(s) in case of disaster recovery (or any other reason). The created template includes the OS disk and other data disks (if any) that are attached to the virtual machine.
It is recommended to perform the Capture operation on the Barracuda Web Application Firewall in the following cases:
- Before upgrading the firmware version.
- Before making major configuration changes.
- After configuring and saving a large set of changes such as an initial configuration.
- As a periodic backup mechanism.
Take a capture
- Log into the Microsoft Azure Management Portal.
- On the VIRTUAL MACHINES page, select the Barracuda Web Application Firewall that needs to be captured.
- Click CAPTURE at the bottom of the screen. The Capture the virtual machine dialog box opens.
- In the Capture the virtual machine window:
- IMAGE NAME – Enter a name for the new image.
- IMAGE DESCRIPTION (LABEL) – Enter a description for the image.
