Im still confused, i need things drawn out for me. So option 1 fully backs up the device partitions without system apps, or just user apps+data? I ask this because i saw that over at XDA News Portal, it says data+apps only but the backup file is about 3.8 GB. Does somebody mind straightening this up?
EDIT: Option 4 (backup apps) doesnt seem to work for my Desire HD. It finishes but the backup file is only 1 KB
