Completely unchecked guessworking - isn't BackupMenu.item (located in /usr/share/backupmenu/ = location that you rm prior to updating) modified to suit multiboot?

Also, Fabry post reminds me of something. When I switched to ext4 for my home, I needed to manually edit backupmenu files to change "ext3" to ext4. no big deal, though, maybe it's possible to - without much time involved - to tweak backupmenu script such a way that they would work for both ext3 and ext4?
