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.

•
•
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

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
