GOOD2USE Knowledge Network Exchange 2000 - Disaster Recovery Tables

PC Knowledge Base - Disaster Recovery Tables

Good Knowledge Is Good2Use

There are different methods you can use to recover a damaged server, a damaged cluster node, or an entire Exchange cluster. The disaster recovery tables shown here provide procedural information about these different recovery methods.

Each procedure listed in the tables contains a link to the section that explains, in detail, how to perform that procedure.
Tip To take advantage of the hyperlinks within these tables, view these tables on your computer instead of in print form.
The disaster recovery tables are divided into the following four categorical tables.

Disaster Recovery Table Description

Table 1: Repairing the Server Contains information about how to fix problems without restoring or rebuilding the server.

Table 2: Restoring the Server Contains information about how to restore a server using a full computer backup set and any other necessary dynamic data backups.

Table 3: Rebuilding the Server Contains information about how to re-install the Windows 2000 operating system, restore the Windows backup set, and then apply any other necessary dynamic data backups.

Table 4: Stand-By Recovery Server Contains information about how to use stand-by recovery servers to speed up or facilitate the recovery process and how to apply backup restorations from the production server to the recovery server.

Disaster Recovery Scenario

To help you understand how to use the disaster recovery tables, consider the following fictitious disaster recovery scenario.

Company Name Exploration Air
Server Recovery Strategy

Exploration Air has a general company policy that instructs its administrators to use the "restore the server" recovery strategy. Exploration Air maintains an inventory of hardware that administrators can use to replace the hardware for each server in its organization. Administrators are also instructed to perform the following backups:

Full computer backup set of the servers running Exchange 2000 once a week (and also following any software updates that are applied) in a two-tape rotation.
Normal nightly backups of the Exchange 2000 databases using Windows 2000 Backup in a seven-tape rotation.

Disaster Occurs

A small computer system interface (SCSI) controller card on one of the servers running Exchange 2000 fails, causing many of the Exchange and Windows services to stop running. Administrators restart the server, but they can only start Windows 2000 in Safe Mode. This leads them to believe that some file corruption occurred.

Selecting a Recovery Option

In an effort to find a solution, administrators browse the disaster recovery tables in this book. After browsing the tables, the administrators conclude that there are two possible recovery procedures they can perform: a Windows 2000 Installation Repair or an Exchange 2000

Member Server Restore.

The recovery procedure that the administrators select depends on the following factors:

If the problem is minor, perhaps affecting only Windows 2000, they should select the "Windows 2000 Installation Repair" procedure in "Disaster Recovery Table 1: Repairing the Server."
If the administrators must restore the entire server and do not want to spend time repairing the server, they should select the "Exchange 2000 Member Server Restore" procedures in "Disaster Recovery Table 2: Restoring the Server."

After running Chkdsk from Windows 2000 Safe Mode, the administrators realize that the file system is severely damaged. Therefore, they decide that performing an Exchange 2000 Member Server Restore is the best solution.

Implementing the Recovery

To recover from this disaster, administrators replace the faulty SCSI controller card, and then follow the recovery procedures in the "Exchange 2000 Member Server Restore" column of "Disaster Recovery Table 2: Restoring the Server."
