Using virtual disk file backups or images for AD disaster
recovery has USN-rollback perils that have been discussed several times here.
It's worth a visit to the archives to check those out before staking your
disaster recovery abilities on this strategy.
On the other hand, using AD-aware backups in conjunction
with virtual servers *does* greatly simplify the hardware issues during a
restore, and may be worth considering for that benefit
alone.

I do a backup of the C: drive and system state using
NTBACKUP to a file on an alternate DC, then I back up the whole DC (files and
system state) using Legato Networker. Why the NTBACKUP? Just in
case...
I've done a couple of hotsite test recoveries of our DCs
(HP DL380G2) to various other HP server models, and even to Dells. I've never
had a major problem doing this with server 2003 (windows 2000, on the other
hand, seemed to always give me grief).
I have toyed with the idea of having a couple of DCs
running on virtual servers. I'd create a perl script to nightly shut down the
DCs, copy the virtual disk files, then bring the DCs back up. I want
to do this not so much for the hardware independence, but rather for the speed
of recovery.

Hello there,
I have a question regarding Active Directory disaster recovery. I was just
curious as to what steps you all take to protect your forest.
An example is I back up my System State nightly and these tapes go off to a
offsite location. If my building and computer suite was to burn down, I would
need to rebuild my forest.
In this scenario I am assuming it would be easier to have identical
hardware to carry out a restore, I know you can restore to alternate hardware
but I hear bad things about this.
The other thought is to have DC built using virtual server and start
this DC one per month to replicate the latest copy of AD, then shutting it down,
saving a copy of the VHD and sending to a offsite location,
That way it's not hardware dependant and just need to do a metadata
cleanup
what do you all do?
