SpycerBox Ultra/Flex Hardware Guide

5.6  Backup or Recovery of the System Disk

The DVS system provides internally a USB flash drive that can be used 
to back up or restore the operating system on the system hard disk. 
With it you can, for example, set the system disk back to its manufac-
turing state. Once selected as a boot device, it will launch a Live Linux 
which in turn will either back up or restore the system hard disk. The 
following sections describe how to create a backup image or perform 
a recovery of the system disk.

5.6.1  Creating a Backup Image of the System Disk

The following describes the steps to make a backup image of the sys-
tem hard disk and save it to the internal USB flash drive:

If appropriate, disconnect all Fibre Channel cables and all externally 
connected storage devices from the system.

Turn on or restart the DVS system and at the indicated moment dur-
ing start-up press [F11] on your keyboard to enter the boot menu.

Once the boot menu is displayed on the screen, select the internally 
installed USB flash drive as the boot device and then press [Enter] 
on your keyboard.

With this the target device has been selected. The system will now boot 
from the internal USB and you will see a window on the screen where 
you can select the DVS Rescue environment for loading:

Select 

DVS Rescue

 and press [Enter] on your keyboard.

Do not execute any commands if you are not sure about the 
correct source and target device. For example, selecting the 
wrong source device could lead to a full storage space and a 
termination of the process.

To complete the loading of the DVS Rescue environment some 
user entries are required. For this follow the instructions given 
on the screen.

The loading of the environment and the process itself will both 
try to initialize hardware that may not be present on your sys-
tem. Any error messages displayed during loading/initializa-
tion, e.g. 

Failed

 or 

Warning

, can be disregarded. The 

backup/recovery process should work nonetheless.

The storage space on the USB is limited. The number of back-
up images that can be stored on the drive, besides the DVS re-
covery image ex factory available, depends on the size of the 
image files. If the process fails, the storage drive may be full. 
However, an already created image can be overwritten when 
assigning the same name to it.
