What is/are the best way(s) of backuping up the Active Directory on a regular basis?
Background: We have a small system with 2 Win2003 Domain controller. We have periodic backups of these machines, and daily backups of the important file share data.
Recently we had 2 failures that lead to a loss of about 2 weeks worth of Active directory, which was a major pain. One of the servers was wiped (by accident), so we recovered it, but a reboot of the other DC showed that the boot drive was corrupted, and rebooted to repeating BSOD. So we had to rely on the two week old backup.
Is NTBackup - System State the only / best method of backing up the AD?
We want a solution that if all the servers die, we can load up a fresh DC and load the AD to a configuration within an hour or two of failure; to minimize re-work and lost data.
