Holy smokes!  :O

There's no critical data on each machine, just some large image files
that could be recreated. The two drives were mirrored so if one failed
I could extract the images, replace the drives, then bring the system
back into the cluster. They were even network booted so even if a
meteor landed on that particular system, I could rebuild the image in
a matter of minutes.
