That sounds nice, but I don't see a RAID-5 controller with a hotswap 
chassis in my future. ;)
I should have mentioned, the down time is not the issue. It doesn't 
matter if the machine is down for weeks. I just don't want to have to 
spend more time than is absolutely required to bring the machine back up.

What you really want is a Raid-5 controller with a hotswap chassis for your

It's expensive, but if you want true single-drive-failure-zero-downtime
operation, it's the way to go, IMHO. Raid5 has saved my butt on more than
one occasion.

Subject: [PLUG] Disaster Recovery Strategies

I have a linux machine that I would like to be able to completely
restore to its current configuration in the event of a hard drive
failure. I'd like to be able to just pop in a new hard drive, and have
it magically work like the old one without the need to manually install
or configure software.
I was thinking about just using dd to copy the entire hard drive on the
currently working machine to a file and then if I ever need to put in a
new drive just using dd to write the contents of the old drive onto the
new drive. Is it a problem if the new drive is a different size than
the old? Or does anyone have a suggest of a better way?
Thanks,
Dave
