It is possible to save a backup file on the Dreambox using Tuxbox Commander without using a PC or FTP.
As this plugin doesn't have a copy file option (at least I couldn't find it), then this method can leave a backup copy on your box for such occasion when the updating is down.
After using your updating plugin, open Tuxbox Commander from the blue button > plugins.
Browse to the subfolder with all the files, select the latest file and change it's name by adding the number 1 (or any other character that you prefere like bu=back up) before the extension.
Exit the Tuxbox commander, use the updating plugin again to create the same working file again.
If you don't have Tuxbox Commander, install it from the blue button > Addons > Gemini Server > plugins
