Mastering Active Directory - Second Edition

AD database recovery

If there is database corruption that cannot be soft recovered (using the preceding method and the ntdsutil recovery command), then you need to recover it from a backup. In order to recover an AD database using a system-state-based backup, we need to use DSRM. The relevant recovery steps using DSRM was explained in Chapter 11, Active Directory Services.

As I mentioned before, AD database issues are very rare in AD environments. If there are any, then you can probably recover from the situation using other options, rather than restoring Active Directory from a backup. This should be the last resort in the troubleshooting process.
