A system state and file restore plan is not enough with a box supporting your AD. Is this another machine bouncing off of your PDC? Worse yet, is this your PDC? I would most certainly have a fully imaged Backup snapshotted every 3 or 4 nights ready to boot and take over if thats the case.
In short....In my opinion, no. To go further, a box supporting AD needs a backup that it fully functional and ready to go. AD will be restored with a file and system state restore but any 3rd party app will be gone. Have you ever done a disaster recovery test? I work for a very large company and we plan for everything, so the experience may be a bit too much for a smaller company. Even still, when I worked for smaller companies with small scale PDCs or Exchange servers, I had a fully imaged backup ready to take over and be fully functional within 3 hours. I was always able to stick with an SLA of a 3 hour restore time too.
