USB Drive Directory Structure

The USB drive contains directories for backup images, configuration files, feature keys, certificates, and diagnostics information for your Firebox.

Device Directories

You can store backup images for more than one Firebox on the same USB drive. When you save a backup image to a USB drive connected to your Firebox, the file is saved in a directory with the same name as the serial number of your Firebox at the root level of the directory structure. When you restore a backup image from a connected USB drive, the software automatically retrieves the list of backup images stored in the directory associated with your device.

For each device, the directory structure on the USB drive is as follows, where <serial number> is replaced by the serial number of the Firebox:

\<serial number>\certs\
\<serial number>\configs\
\<serial number>\feature-keys\
\<serial number>\flash-images\

The backup images for a device are saved in the \<serial number>\flash-images directory. The backup image files saved in the flash-images directory contain the device configuration, feature keys, and certificates.

The \configs, \feature-keys, and \certs subdirectories are not used for any USB drive backup and restore operations. You can use these directories to store additional feature keys, configuration files, and certificates for each device.

auto-restore Directory

A directory at the root level of the USB drive directory structure is used to store auto-restore backup images:

\auto-restore\

When you designate a backup image to use for automatic restore, a copy of the backup image file is encrypted and saved with the file name auto-restore.fxi in a subdirectory for your Firebox model below the \auto-restore\ directory. For example, \auto-restore\T35\auto-restore.fxi. You can save only one auto-restore backup image for each Firebox model on each USB drive.

Do not use a backup image created from a different Firebox for auto-restore. The auto-restore backup image is unique to a single Firebox, and includes the serial number, certificates, and private keys unique to that Firebox.

To create a backup image for auto-restore, you must use one of these methods:

  • From Fireware Web UI, select System > USB Backup and Restore Image.
  • From Firebox System Manager, select Tools > USB Drive.

If you manually copy and rename a backup image and store it in the auto-restore directory, the automatic restore process does not operate correctly.

wgdiag Directory

A directory at the root level of the USB drive directory structure is used to store the support snapshot:

\wgdiag\

The support snapshot can be used by WatchGuard technical support to help diagnose issues with your Firebox.
