That's a good point. I could plan on a system reboot to coincide with
the disk swap (it is Microsoft, after all). But, aren't server drives
made to be hot swapped?
Either way, the model still stands. From the outside looking in,
mirroring the hard drives with hardware seems the easiest method to back
up the data. With two back up drives, I could power down the system and
switch back up disks once a month--one on the shelf and one in the
machine. And recovery would be easy, too. I could just swap the
primary disk with the back up disk on the shelf...
I just don't know if the Invensys configuration would have a problem
with this solution.

Hi all,
>Does anyone know a reason it wouldn't work?
I'd never trust the data stored on a harddisk pulled out without
shutting
down anything on a running windows system.
Be careful: "Hot swappable" means that the electricity involved
(harddisk,
controller) does not get harmed by hot swapping disks. It does NOT mean
data
consistence in swapping at arbitrary stages of the file system.
