Exchange /DisasterRecovery Switch

Posted on 2007-11-24

I run Exchange 2003 and actually want to use the Disaster Recovery Switch on it due to hardware failure of the D:\ which contained the Exchange installation path.

Im a local admin with rights to install software but not Exchange due to it modifying the configuration information in Active Directory.

My question is since the Recovery Switch does not modify the config in AD will I be able to do this myself?

In theory, no.  You might want to try installing it.  The installer normally blocks if the correct rights aren't present.

MS KB article says:

setup.exe /DisasterRecovery
Allows recovery of an Exchange installation after the server configuration has been restored from backup. This allows you to recover data from missing files, registry keys, and deleted folders. You must make sure that there is a valid backup of the data, and if there is not a valid backup, check to make sure that the databases that are located on the server are consistent. You should not use this switch to upgrade Exchange 2000 Server to Exchange Server 2003. This switch is read-only and makes no changes in Active Directory.

Thanks for that info however; I'm not actualyl trying to backup data or mailboxes. All I'm doing is installing fresh drives without decommisioning. This way I can have the same name and everything else without having to go through a complete install. Again, the stores are empty

Unless you can restore the application files from a backup, you'll still need to go through this process with the /disasterrecovery switch.

You can always delete and recreate the storage group and/or stores when you are done, so there is no need to recover from backup.

Oops I said backup I meant restore. I don't need to restore anything. I just need to pull drives and recover using the switch without actually decommisioning the server.

So it sounds like you said thats all good correct? Answer this and I will close this post.

Thanks a lot
