I know this nice long detailed guide
… and many docs for the blue ring under http://mybookworld.wikidot.com
But all rescue procedures use backup files as intermediate step
I can't find a simple script, to clone a healthy running MyBook-HDD to an external USB HDD as bootable backup. (live backup of disk)
I think it will do a simple dd if=/dev/sda of=/dev/sdc .
How to resolve the problem, that dd copying must be done on unmounted disks/partitions?
It's better to use rsync to copy a mounted partion?
How I can use another drive size for sda4 ?
PS: On my clean book I' dont like an installation of the suite "Feature Pack Installer" with the part "MybookClone Feature Pack".
