[cobalt-developers] Backup and Migration

[Fraser Campbell <fraser@xxxxxxxxxxx>]

Hi,

We have 2 RAQ1 servers and 1 RAQ3 server.  All servers are seriously
damaged due to an unscrupulous administrator and need to be reinstalled.

We wish to upgrade the RAQ1s to RAQ2 software.  Is there a way to
temporarily migrate sites from a RAQ1 to a RAQ3 and then move them back to
a RAQ2 after we've upgraded.  I don't see any way of doing this easily so
our intention is to move the sites temporarily to a vanilla redhat server
and then back to an upgraded RAQ.

How have others handled this?  The CMU scripts don't seem to be available
for RAQ1 and it also doesn't look like they'd let us go the RAQ3->RAQ2
route.  Any ideas?

Also once we upgrade the machines what is a good backup policy?  We want to
use an Amanda server (on a remote Redhat machine) and  backup using an
Amanda client on each RAQ.  What must be backed up to make restoration a
plug-and-play procedure?
