asked on Restoring Virtualized Win2k8 DC from backup
Ok, we are backing up our VM DC's every 2 hours.
Should we need to restore one from backup how long can AD be down for and will we experience problems should we restore from a 2hr backup? Will take a minute to restore.
and
Should we lose a DC and not be restored within hours or days what is required to restore the DC? I assume build a new VM and add as a DC and forcibly remove roles from AD?

I would recommend a Backup, just in case.

in case?
If it blue screens or someone deletes the VM, then restoring it a few hours later will be ok then?

Yes, split DNS and DHCP...
yes, you can do that, restore.

But as per neil, surely its at risk of causing issues with AD?

What triggers the event ids and issues with AD? The amount of time? The amount of changes made within the database(s)? Replication?
Not sure what you mean: If you have two DC's and one goes down you can start 2nd DC in 30 Mins thats't too without disrupting services

So consensus is to back them up but in real world you wouldn't restore them, ever. If failure occurs, build new DC, seize/transfer roles and clear old metadata from AD of failed DC?
Yes but the backup is taken incase you have any rarest of the rare event when both of your DC's are down
ASKER
continuing with backups, every 2-3 hrs, but understand that if the dc fails that we probably wont restore from the backup, unless a last resort.
So no need to backup then? Using acronis... Not sure what you mean by system state..
