I have two identical HD in the box and want to duplicate sda to sdb;
sdb is not even partitioned.
I think I could do:
dd if=/dev/sda of=/dev/sdb
but I need to boot from CD isn't it?
I would like the second disk to function as an identical bootable backup (just
in case something will malfunction after emerge :-/)
So I would normally boot from sda but have an ability to boot from sdb, just in
case)
So after duplicating the disk I would need to modify the grub, fstab on sdb
hard disk.
I'm not even sure if it will do what I need. What are my other options RAID-1?
RAID-1 will not protect me if something happens after emerge.
