To create a backup copy of the firmware, plugins are used, which are usually preinstalled in the firmware:
Backupsuite – plugin to create a backup copy of the firmware for all models of boxes, except DreamBox.
dFlash – plugin to create a backup copy of the firmware for all DreamBox models.
There is also an alternative, not preinstalled plugin:
FullBackup – plugin to create an automatic (under the schedule) backup firmware for all models of boxes.
The menu for calling these plugins is in [Settings] -> [Up sub menu (2 times UP arrow)] ->[Flashing & Backup]
