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