Recovering from a full server failure

Recovering a full server failure involves a fresh reinstall. Get the most important points to consider.

The disaster recovery method outlined in this my tip on taking the sting out of Exchange 2007 disaster recovery is just one example of how to recover from a corrupted database. Recovering from a full server failure involves a fresh install. Following are a few key points to keep in mind if you need to recover from a complete server failure.

  • Reinstall the operating system to the same service pack and patch levels as the previous OS.

  • Configure the LUNs so they are identical to the previous server’s LUN configuration.

  • Give the server the same NETBIOS name as the previous instance.

  • Reset the domain computer account of the failed Exchange Server in Active Directory.

  • Join the new server to the domain.

  • Install Exchange Server using the Setup.com /M:RecoverServer switch.

  • Bring Exchange up to the service pack and roll-up level as it was in the previous installation.

Recover your databases to the correct locations by choosing the “Files and Folders” option in the backup utility, not the “Application” option.
