after thinking for backup options i found out:
You could clone an entire harddisk to another harddisk if
its the same size with the command dd.
For cloning a harddisk to an smaller one you should use
dump (saying on groups.google.com).
So i searched and found out more:
use an linux-cd or an rescue-linux-disk with the rescue
So what are the commands for dump to clone
harddisk /dev/hda with 5 partions to hardisk /dev/sda
Should i use fdisk and create the partions?
Thanks a lot!
