How to Create an ASR Backup of the Primary Server to Restore to the Secondary Server



This Knowledgebase article provides information on how to use an Automated System Recovery (ASR) restore procedure for the installation of Neverfail Heartbeat.

More Information

The restore procedure uses an Automated System Recovery (ASR) to backup the Primary server's data and system state so that they can be then restored to the Secondary server instead of using the clone file.

The ASR process allows restoration of the system disk (usually the C: drive) including the Windows files, Registry settings, and all user programs and data, allowing you to recover a completely crashed system. To use this procedure you must be able to boot the Windows 2003 Server Setup program from the installation CD-ROM.

During the restore process, all data previously found on the System partition (usually C:\) will be erased and Windows 2003 Server will be reinstalled, and the data from the ASR backup will be restored.


In order to use ASR you first need to create the ASR backup. Follow these steps:

  1. Run NTBACKUP.EXE from the Run command or from the Program Files > Accessories > System Tools .
  2. Clear the 'Always start in Wizard Mode' check box and click Cancel .
  3. Repeat step 1 and then skip to step 4.
  4. When the program starts click on the ASR button to invoke the wizard.
  5. The Wizard will start with a Welcome screen, advising that a Backup and the ASR disk will be created. Click Next .
  6. Choose a destination and filename for the ASR backup and ensure that you have enough free disk space for the ASR backup file on that partition.
  7. The 'Completing the ASR Preparation Wizard' will appear. When you click Finish , the wizard creates a backup of your system files. You will then be instructed to insert a floppy disk. You will later use this floppy disk and the ASR backup file to restore your system in an event of a major failure.
  8. To close this wizard and to begin the backup, click Finish ".
  9. The system will create a list of all files and then start the backup processes, creating a disk-backup-file. Once the disk-backup is complete, you will be prompted for a floppy disk (blank, formatted) to store some ASR-data.

After completing the backup process, use the ASR backup to restore to the Secondary. The Secondary should have a fresh installation of Windows 2003 with all patches, updates, and hotfixes current to the state of the Primary prior to enacting the restore process.
