Restoring from a Backup

Backing up your data is only half the picture. The other half involves restoring files on the network. We hope that you have to restore only a few files for users from time to time. Making regular backups along the way makes this task friendly and easy. However, in a fire or other disaster, you might lose your data and computer equipment, including the server to which you need to restore. We hope that you heed our advice when we say to rotate tapes offsite each week to plan for this catastrophe. If you also lose the server, we hope that you have a good working relationship with your local vendors so you can get equipment in a hurry.

The most important thing to remember when restoring your network is to practice the restoration process when you're not under the gun. This not only gives you confidence in performing the task, but also periodically tests the integrity of your backup. Although you can examine log files each morning, it's better to perform real restore tests - just like a dress rehearsal. When disaster does strike and you need to perform a real restore, all sorts of people will be looking over your shoulder asking you when things will be up and running. If you confidently know your backup system, you can perform this task under extreme pressure. Don't wait until the last minute to test and learn the system.

Always restore the system files (\SYSTEM32\CONFIG and Registry files) first, reboot, and then take a peek at the system to make sure everything looks like it's in place. Then restore the data files. If you plan your network directory and volume structure to segment system and data files, this task is much easier. Know ahead of time whether certain business departments require that their data be restored first. Sometimes this is not necessary, but in instances where a customer service department exists, they usually want the network back up right away with immediate access to their data. Why? Because they're servicing the external customers that generate the revenue for your organization! Before restores become necessary, try to devise a restoration order plan for your network and practice it.

Note that sometimes you can't restore Windows 2003 system files; you may have to reinstall Windows 2003, and then restore the system files.
