5.10 Firmware
The appliance supports the storage of two firmware images. These images behave similar to different OSs on a dual-boot
system that combines the OSand configuration. When upgrading the firmware from the DSView™ management software or
the web UI, the appliance will copy the active configuration into the new firmware image slot and combine them with the
new firmware OS.
After installing the new image file, the appliance will reboot to the second firmware image slot. The configurations in image
slot 1 and 2 are the same, but all subsequent changes will only be made into the currently booted image. If you experience
issues with the new firmware image, you can reboot to the older image.
As the firmware is upgraded, the oldest image will be overwritten with the new firmware.
From the sidebar, click Firmware to view the current firmware version, upgrade to the latest version, back up or delete the
firmware.

5.10.1 Backing up and restoring appliance configuration
An administrator can create a backup of the appliance's configuration. The backup file will reside inside the appliance but
must be downloaded to your local machine or network share before it can be used.
Saved configuration files can only be applied to an appliance running the same firmware version as the appliance the
configuration file was taken from. It is recommended you save the configuration file each time after you upgrade the
appliance firmware.
To back up the appliance configuration:
1. From the sidebar of the Administration tab, click Firmware.
