Intelligent Disaster Recovery  
The Intelligent Disaster Recovery Option saves recovery time by automating the traditional  
manual, error prone process. This option automates server recovery, reducing the time to recover  
and gets business back into production fast.  
Using either a CD-R/CD-RW or bootable tape, the Intelligent Disaster Recovery Option will quickly  
recover downed servers enabling restores from the last complete backup set including full,  
differential, incremental, and working set backups.  
How Intelligent Disaster Recovery Works  
The Intelligent Disaster Recovery Option is designed to protect Microsoft Windows operating  
systems. There are unique challenges in protecting these environments that are discussed in the  
section, “Intelligent Disaster Recovery for Different Platforms and Windows Operating Systems”.  
The Intelligent Disaster Recovery Configuration Wizard appears the first time Backup Exec is  
launched from the Dell Appliance Management Console. The wizard systematically guides a user  
through the steps necessary in preparing for a disaster recovery and in recovering a local or  
remote Windows system to its pre-disaster state. A complete Intelligent Disaster Recovery  
Operation consists of the following 3 steps:  
1. Creating a Disaster Recovery file that contains specific information about the  
protected computer.  
2. Making a full backup of the system being protected.  
3. Creating bootable Disaster Recovery media for the protected system.  
Step 1: Creating a Disaster Recovery File  
The Disaster Recovery File contains specific information about the individual system that is being  
protected. This information includes:  
Hardware specific information for each system including hard disk partition  
information, mass storage controller information, and Network Interface Card  
information.  
The list of catalog entries that identify the backup media and sets needed to recover  
the system in the event of a disaster.  
Windows Automated System Restore (ASR) configuration for Windows XP and  
Windows Server 2003 systems.  
1. On the Backup Exec Getting Started screen, select “Configure Intelligent Disaster Recovery”  
to start the wizard. When the Welcome screen appears, click “Next” to continue.  
Backup Exec automatically creates a *.dr file for the IDR-protected computer when it is backed up  
and stores it in the default location on the media server’s hard drive, which is:  
C:\Program Files\Symantec\Backup Exec\idr\Data\<computer name>.dr.  
The “Enter an Alternate Data Path” screen allows you to specify an alternate location for storing a  
copy of the *.dr. This allows the *.dr file to be available even if the media server has been  
damaged.

2. Enter the alternate location where a copy of the *.dr file will be stored, and then click “Next”.  
Best Practice: Symantec recommends that the alternate location be on another computer or on a  
different physical drive than the default location.  
3. The IDR configuration is now complete. You are ready to run backups and create bootable  
media. Click “Finish”.  
Step 2: Running a Full Backup  
After creating the Disaster Recovery File, a full backup of the hard drives on the protected system  
needs to be performed. Make sure that the full volumes are selected (C, D, etc.) for the backup.  
By selecting the full volumes, the disaster recovery file for the specific machine will be updated  
with the latest system information. In addition to selecting the full volumes, make sure the  
following Best Practices are followed:  
Select the utility partitions, if present, for backup on the protected system.  
Do not utilize the” include or exclude files” feature. This is located in the Advanced  
File Selection of the backup job properties.  
If a remote system is being protected, make sure that the Agent for Windows  
Systems is installed on the remote system.  
1. On the Backup Exec interface, select the drop down from the Backup Tab and choose “New  
Backup Job…”  
2. The Backup Job Properties page will appear. Verify that the remote agent is installed by  
right-clicking on the system name in the View by Resource tab and select Properties. The  
status of the remote system is displayed. Verify that the following appear for the Remote  
Agent status:  
Installed: Yes  
Status: Running  
Version: 12.5.x.x  
If the Remote Agent is not installed or running, refer to the Backup Exec Administrator’s  
Guide for steps to install the Remote Agent for Windows Systems.  
3. After verifying that the remote agent is installed and running, select the remote system for  
backup at the system name node. In addition, a selection list name and description can be  
specified so that the selection list can be reused in additional backup jobs.  
4. The destination for the backup job can be specified from the Device and Media tab. The  
default device is “All Virtual Disk”. The backup job will target any available virtual disk as the  
backup destination.  
5. Name the backup job from the General tab. Naming the backup job provides an ease of use  
mechanism for remembering the purpose of the backup job in the future.  
6. A schedule can be created so that a backup job repeats on a periodic basis, ensuring that a  
system is protected with the latest information. For the purpose of this article, the backup job  
will run immediately with no schedule set. Select “Run Now” and select “Ok” from the Job  
Summary to run the backup.

The backup job status can be monitored from the Job Monitor tab on the Backup Exec interface.  
The backup job has completed successfully when the backup job appears under the Job History  
and is listed as Successful.  
Step 3: Preparing Disaster Recovery Media  
1. From the Tools Menu, Select “Wizards” and then select the “Intelligent Disaster Recovery  
Preparation Wizard.”  
2. Select “Next” to continue the wizard.  
3. Select the type of media that will be used to create the DR media:  
Bootable CD Image for Use with CD Writers (ISO 9660)  
Bootable Tape Image for use with bootable tape devices  
Non-bootable disaster recovery CD Image  
Or Copy  
Disaster recovery information (.dr) files  
BEST PRACTICE: Creating a bootable CD image provides the quickest methodology for  
performing the recovery of a failed system. Backup Exec will create an image that must be  
burned to CD using third party software. A blank CD, third party software, and a writable CD  
device must be available. For the purpose of this article, a bootable CD Image will be used.  
4. Select “Bootable CD Image” for Use with CD Writer (ISO 9660) and select Next.  
5. Select “Next” to continue the CD Image Creation Wizard.  
6. Select the systems that you want use for recovery with the bootable CD Image. Move each  
system from the list of Available Computers to the list of Selected Computers. NOTE: All of  
the selected computer must be running the same version of the Windows operating system.  
Select “Next” to continue.  
7. Specify the location that Backup Exec will create an ISO 9660 CD image. Select “Next” to  
continue.  
8. Backup Exec utilizes the Windows operating system installation files in the creation of the  
IDR recovery media. The Windows operating system files provided must match the version  
and language of the systems being protected. Specify the location of the Windows operating  
system installation files and select “Next” to continue.  
9. The Intelligent Disaster Recovery Wizard will create the bootable CD image. This may take a  
few minutes. When complete, the ISO image will be stored in the location specified in step 7.  
Select “Next” to continue.  
10. The ISO image must be burned to a CD using third party software before it can be utilized as  
part of the disaster recovery process. Select Finish to complete the IDR Preparation Wizard.  
Recovering a System  
In the event that a protected system experiences a disaster or system crash, it can be recovered  
in the following 2 steps:  
Boot the failed system with the Disaster Recovery CD Media that was created with the IDR  
Preparation Wizard  
Recover the system and data to utilizing the Disaster Recovery Wizard

13. Once the data has finished restoring, the disaster recovery process will be completed. If the  
restore was performed to a different system, it may be necessary to specify the correct hard  
drive to boot the operating system. This can be done by editing the BOOT.ini file. If no  
changes are needed, select “Finish” to complete the disaster recovery process. The system  
will now reboot.  
14. The disaster recovery process is complete.  
Important Considerations  
Intelligent Disaster Recovery for Different Platforms and Windows Operating Systems  
Some Windows operating systems have certain caveats that need to be understood before  
implementing an Intelligent Disaster Recovery solution.  
Windows 2000  
Windows 2000 has several components that make up the System State and these components  
must be backed up together. Critical to the recovery of the system is the restoration of the  
Systems State, which replaces boot files first and commits the system hive of the registry as the  
final step in the process. Backup Exec provides full protection for Windows 2000 System State,  
which includes:  
Registry  
COM+ Class Registration database  
Boot and system files  
Certificate Services database for systems operating as a certificate server  
Active Directory for Domain Controllers  
SYSVOL – System Volume for Domain Controllers  
Cluster quorum for Cluster Servers  
Proper handling of backup and restoration of System State is key to the successful  
recovery of any Windows 2000 system; therefore, an automated disaster recovery  
solution is ideal for the complex process of recovering any Windows system.  
Windows XP and Windows Server 2003  
Windows XP and Windows Server 2003 systems include Windows Automated System Recovery  
(ASR) technology. Developed by Microsoft, ASR enables disaster recovery of the operating  
system. The Intelligent Disaster Recovery Option works with ASR for reconfiguring the physical  
storage to its original state following a disaster. This information includes:  
OS Version  
Time Zone  
Buses  
MBR disks and partitions  
GUID Partition Table disks and partitions  
Recovery commands  
Removable media information  
LDM Volume State  
Device instances  
Class Keys  
Device instance hash values  
Backup Shadow Copy Components for Windows 2003
