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?
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
So no need to backup then? Using acronis... Not sure what you mean by system state..
