Subject: [gentoo-user] Duplicate identical Hard Disk
Date: Thu, 1 Apr 2010 16:48:20 -0600 [thread overview]
Message-ID: <20100401224820.GA5637@syscon4.inet> (raw)
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.
