Thats some of what I need to know. I have been working on the server backup.
I was wondering if the raid set up would do what I needed. What I am
thinking is that with Raid1, can I unplug one drive ,then plug in another
and use that as a backup disk? Will the Raid build the new drive that I put
in place? I have read a bunch about Raid but it dont answer these questions.
Or am I thinking wrong?

Did you look at
http://www.tldp.org/HOWTO/Software-RAID-HOWTO-1.html#ss1.4 already?
If a raid array is degraded by the complete loss of a drive, it
(software raid as described in the howto) won't automatically restore
it after it is reconnected.
see http://www.tldp.org/HOWTO/Software-RAID-HOWTO-6.html#ss6.3 for
info on how to simulate a failure.
We have a talk on LVM available in our archives, too. You might be
interested in doing raid + LVM.

I have read some about Raid. Please explain what happens with Raid
1(mirroring). Does it do this automatically or something has to be done
for
the working drive to take over? What would happen if I disconected one of
the drives in a Raid1 config? Would the other drive automatically take
over?
After the disk is put back in will the Raid update the drive to match the
first one?Automatically?
