Hi Allend, thanks for the reply.
It seems pritty straight forward, but my life was in pretty much a misery when an restoration failed to boot up (this was long time a go so I can't remember the exact error)
. What I did was do a dd if=/dev/sda of=disk_backup and to restore dd if=disk_backup of=/dev/sda. This command should copy block to block of the first drive to the second, dont know what went wrong though.
I was under the impression the hardware has to be identical for an dd dump to be perfect (32 and 64 has to match of cause)!
Thanks again and best regards
