You are definitely making your life more difficult then is needed for a desktop machine.<BR>
<BR>
You said you have 4 hard disks. Make a software RAID1 out of the first two. Make a software RAID1 out of the second two and your good to go.<BR>
<BR>
You can use dump/restore to backup the logical volumes on the second<BR>
RAID set to an LV on the first.<BR>
<BR>
No need for bare metal restore. Just need to get some working Linux distro to be able to read your files.<BR>
<BR>
Going HW RAID for your desktop is going to get in the way of you getting things going and if your HW RAID card fails then what? Your drives will only work with another identical HW RAID card.<BR>

This might be getting a bit elaborate for a desktop machine. I really want RAID because<BR>
I'm tired every couple years of hard drive crashes and having to start from scratch and<BR>
spending a week setting up new drives and getting my design software back on line and trying<BR>
to recover data.<BR>
<BR>
What do you think of alternative back up systems, such as a tape backup with<BR>
bare metal restore software? I'd go that route instead if I could fine a solution which<BR>
would allow me to restore to different hardware, i.e. if my motherboard dies<BR>
and I need to buy a different brand or model MB. I know Storix back up software<BR>
has this capability - I use storix on my Linux server with RAID 1. @ home I have<BR>
one Linux and one Windows desktop machine.<BR>
