As asked by Pali I created an updated package (1.1.1-2) which includes the modified backupmenu.item. If the latest version 1.1.1-1 is installed, only this single file should be updated in the process.

edit: link removed because it is now picked up by the author himself.

During boot with keyboard slide out, bootmenu should start and present you with the option to start backupmenu as one of the choices.

Please report any issues if found.
