We're installing Microsoft Data Protection Manager 2007 - we'll be using it to back up Exchange and SQL Server among other things.
Does anyone know if DPM can also back up Active Directory?
It sounds like the answer is "not really". You can install the DPM agent on a domain controller and make system state backups. But if your Active Directory is out of commission, there will be no way to restore the backups, since DPM depends on AD.
Currently we're just using Windows Backup (ntbackup) to take system state backups on one of the DCs. Should we just continue with that?
