If you're about on irc at all tomorrow I may pick your brains about your
experiences. I kind of ruined my test environment this afternoon. I had
to redeploy about 15 virtualized guests on my tiny microserver at home.
That took quite a while ;-)

physical parts of the hds ie platters and arms should survive
that.....electronics might as well.....in which case swapping one half
(I assume you have a raid1) to a new box and syncing it might
work....then drop out the old disk and slot in a new one...same with
fire / smoke damage. NB One of the recommended ways to put out a fire in
a server room is water misting using de-mineralised water....

I was merely giving a radical scenario in jest. My main purpose is to
produce an IPA 'specifc' backup/restore procedure that doesn't rely on
other technologies. Starting with a similar goal to restoring an AD
system state backup for example.

2gb....not much disk use....use kvm and gluster might work well. The
second machine could be a reasonable spec'd desktop....like <$2k should
be good enough....

is to avoid having a NAS and that expense....so 2 ESXi boxes running a
gluster node on each and then the rest of the VMware guests inside
gluster's "disk". Another way might be rsyncing the ldif over ssh to a
remote site......maybe even email it to say google....it shouldnt be
very big, ours is 400k at the moment.
