vi Disaster Recovery Option Guide
Chapter
Introducing the Option
1
BrightStor® ARCserve® Backup is a comprehensive, distributed storage solution
for applications, databases, distributed servers, and file systems. It provides
backup and restore capabilities for databases, business-critical applications, and
network clients.
Benefits of Using the Option
Disaster recovery is a backup and recovery process used to protect computing
environments against the loss of data caused by a catastrophic event or natural
disaster. Disasters can be caused by fire, an earthquake, employee sabotage, a
computer virus, or a power failure. By their very nature, disasters cannot be
predicted, in their intensity, timing, or effects.
When a mission-critical server goes down, only one thing matters—time. Each tick
of the clock means business lost, opportunities squandered, efforts wasted. You
need to get your system back online quickly, accurately, and safely.
BrightStor ARCserve Backup Disaster Recovery Option does this for you.
The option allows you to quickly and easily restore a server without the need for
re-installing the operating system. It supports one-button disaster recovery
(bootable tape) in a Windows 2000 environment. It supports diskette based
disaster recovery in Windows NT and Windows 2000, and CD based disaster
recovery in Windows 2000, Windows XP, and Windows 2003 environments.
There are many time consuming tasks—including installation of the base
operating systems and setup of the server—that would usually have to be
manually performed after a disaster. The option enables you to restore your server
with minimal effort and reliable recovery. It lets you make more efficient use of
time by taking you from boot media, to backup media, to online, faster than other
solutions.
The option enables users with minimal server configuration experience to recover
sophisticated configurations.
Introducing the Option 1–1
Understanding How the Option Works
Understanding How the Option Works
The option is based on the concept of collecting and saving machine-specific
information before a disaster strikes. Whenever a full backup job is submitted, the
option automatically generates and saves emergency data information for the
node, locally on the backup server, on backup media, and, if configured, on a
remote computer. In the event of a disaster, the option can recover its protected
computers to their last full backup state. Therefore, the recovery depends on the
availability of full backup data.
Note: The option generates or updates emergency data information for disaster
recovery only when performing a full backup of the machine.
Features and Functionality
The option is a flexible, easy-to-use, enterprise-wide solution to protect your data
on Windows NT 4.0, Windows 2000, Windows XP, and Windows 2003 based
machines. The option provides you with the following features and functionality:
■ It protects your local BrightStor ARCserve Backup server and remote
Windows NT 4.0, Windows 2000, Windows XP, and Windows 2003 clients
®
backed up by the BrightStor
ARCserve® Backup Client Agent using
BrightStor ARCserve Backup Server for Windows.
■ You can quickly put an unusable system back online, saving you substantial
time compared to recovering your system in the traditional method of first
reinstalling the operating system and later configuring it. There is no need to
reconfigure the system before it is usable when you use the option.
■ The option works with minimal user input. It can support any system that
BrightStor ARCserve Backup supports. The aim is to protect the server on
which BrightStor ARCserve Backup and other important applications are
running. The option effectively restores the server, provided the
recommended measures were performed before the disaster occurred. It can
also protect remote Windows NT 4.0, Windows 2000, Windows XP, and
Windows 2003 platforms.
■ The option is compatible with previous versions of BrightStor ARCserve
Backup. You can use the option with BrightStor ARCserve Backup version 9
agents. In addition, you can use the option with BrightStor ARCserve 2000
with Service Pack 4, although you must run new backups.
1–2 Disaster Recovery Option Guide
Disaster Recovery Methods
Disaster recovery methods are provided for specific versions of Windows as
discussed in the following sections. For more information about the differences
between the methods discussed in this section, see the “Recovering from a
Disaster” sections in the
on Windows 2000", and "Disaster Recovery on Windows XP and Windows 2003"
chapters in this guide.
Windows NT and Windows 2000
On Windows NT 4.0 and Windows 2000 platforms, the option provides three boot
methods for disaster recovery:
■ Bootable disk method: Using a modified version of the Windows NT 4.0 or
Windows 2000 setup disks, you can recover any computer using the Disaster
Recovery Wizard. You can start up any server, including servers with
unformatted hard drives, and fully restore your system using the option’s
backup media.
Disaster Recovery Methods
"Disaster Recovery on Windows NT 4.0"," Disaster Recovery
Note: Only remote disaster recovery is supported on Windows NT. Local
disaster recovery is not supported.
■ Bootable CD method (preferred method): For Windows 2000, the option has
a faster way of booting to the Disaster Recovery Wizard. Instead of using disks
and a Microsoft 2000 CD, you need only one disk and a recovery CD. The
wizard then restores the system using the option’s backup media.
■ Bootable Tape method (Windows 2000 only): Instead of booting from a
floppy disk drive or CD, you can boot Windows 2000 based servers using a
tape drive. Recovery can be performed directly from the backup tapes. The
option creates a bootable backup tape for use with compatible tape drives and
only requires the most recent backup media.
Note: Tape drives must be configured to act as boot devices. Because tape
drive functionality varies by manufacturer, contact your tape drive vendor to
determine if your tape drive capabilities meet your needs.
Windows XP and Windows 2003
The option supports local and remote disaster recovery, allowing you to get
Windows XP and Windows 2003 configurations back online quickly, accurately,
and safely. To do this, you must have the following:
■ Windows XP or Windows 2003 CD
■ A machine-specific recovery disk
■ The BrightStor ARCserve Backup CD
Introducing the Option 1–3
Disaster Recovery Methods
Note: The Window XP or Windows 2003 CD used to perform disaster
recovery must be the same version used to install the original system.

1–4 Disaster Recovery Option Guide
Creating a Disaster Recovery Test Plan
As part of disaster recovery preparations you should develop a disaster recovery
test plan. To test your plan, complete the following steps:
1. Create a set of disaster preparation materials to be kept off site and be sure you
know where they are located. Follow the instructions in the subsequent

Creating Bootable Disks
Bootable disks for Windows 2000 and Windows NT 4.0 are created in the following
ways:
Creating a Disaster Recovery Test Plan
■ On Windows 2000: Create the boot disks for Windows 2000 using the
MAKEBT32.EXE command in the Windows 2000 CD BOOTDISK directory.
■ On Windows NT 4.0: The boot disks for Windows NT 4.0 can be created in one
of the following ways:
– Create the disks using the WINNT32 /OX command in the Windows
NT4.0 CD i386 directory. This is the recommended method to create the
boot disks for use with the option.
– Use the DISKCOPY utility to create copies of the original setup disk that
came with the Windows NT 4.0 CD. We recommend that you use the
DISKCOPY utility rather than the commands XCOPY or COPY to create
these disks.
Note: These procedures create disks containing a modified version of the
setup software and configuration for a specific machine. If you use the disks
created during the CD installation of Windows NT, the disaster recovery
process fails.

Preinstallation
The following chapter discusses information you need to have available when you
install the option, the procedure to install the BrightStor ARCserve Backup
Disaster Recovery Option, and post-installation considerations to help you
fine-tune the option after it is installed.
This section describes information you should review before installing the option
and information you must have available when installing the option.
Prerequisite Software
Verify that you have BrightStor ARCserve Backup installed before installing the
option.
Documentation
Before you install the option, we recommend that you review the following
documents:
■ Readme file—contains the operating system requirements, hardware and
■ Getting Started—provides an overview of product features and functions,
■ Release Summary—lists new features and changes to existing features that
software prerequisites, last minute changes, and all known issues with the
software. The readme file is provided in HTML format and is located at root
level on the product CD.

are included in the release. The Release Summary is provided in PDF format.
Installing the Option 2–1
Preinstallation
Installation Type
You can choose one of the following installation types:
■ Local installation (default): Choose this installation type to install the option
on the local (current) computer.
■ Remote installation: Choose this installation type to install the option on a
remote (different) computer.
■ Silent installation: Choose the option Create a Response File to specify silent
installation. If you select this option, you can click browse to alter the location
where you will save the response file.
Alternate Location for Disaster Recovery Information
When you back up a local or remote BrightStor ARCserve Backup client computer
using the option, the computer-specific information required to perform disaster
recovery tasks is saved on the BrightStor ARCserve Backup server.
If the BrightStor ARCserve Backup server fails, computer-specific disaster
recovery information can be lost as well. To avoid this type of data loss, the option
can store machine-specific disaster recovery information to a remote location on an
alternate computer. This feature allows you access disaster recovery information if
the BrightStor ARCserve Backup server fails.
If the server fails, you can access the alternate location to create machine-specific
disks. The alternate location has a directory with the same name as the machine or
machines you are recovering. Copy the contents of this directory to a disk. The
newly created disk becomes your machine-specific disk.
Note: When you back up a Windows XP or Window 2003 based computer, the
option creates a drpatch.xp folder in the alternate computer location directory.
Copy the files in the drpatch.xp folder to the machine-specific disks.

Windows NT 4.0
To prepare for a disaster, (defined as the loss of at least the server’s Windows NT
4.0 system volume) use the disaster recovery process described in this chapter. The
disaster recovery process is a two-step process—preparation and recovery.
Note: Only remote disaster recovery is supported on Windows NT. Local disaster
recovery is not supported.
Creating Boot Media
You can use the Bootable disk method to create bootable media to bring your
server back online quickly. The Bootable disk method uses 3.5-inch disks. The
disks contain a modified version of the Windows NT setup software and
configuration information for a specific machine. These disks enable you to start
any server (with or without a formatted hard drive) and fully restore the system
using backup media. The Windows NT CD is required during the recovery
process.
Note: You can create boot media at any time, even after the system has failed.
However, you must make sure that the machine has been fully backed up by an
available, functioning BrightStor ARCserve Backup server.
To protect your BrightStor ARCserve Backup server itself, you must create boot
media before a disaster occurs, or use the alternate location feature. For more
information about this feature, see the section
in the “Installing the Option” chapter of this guide.

Recovering from a Disaster
This section describes how to recover from a disaster using the bootable disk
method.
Recovering from a Disaster Using the Bootable Disk Method
To recover from a disaster, you need the following:
■ A set of BrightStor ARCserve Backup disaster recovery boot disks. These are
the disks that you created following the procedure in the section
a Disaster Using the Bootable Disk Method in this chapter.
■ A Microsoft Windows NT CD matching the version used to create the boot
disks.
■ A backup device connected to a remote BrightStor ARCserve Backup server
with BrightStor ARCserve Backup media or MTF (Microsoft Tape Format)
tape, containing the data you want to restore in the drive. The media must
contain at least one full backup of the machine that you want to restore.
Preparing for
Note: Special partitions such as Extended Industry Standard Architecture
(EISA) or Industry Standard Architecture (ISA), which can be seen from fdisk
or windisk.exe, should be configured properly before the disaster recovery
process, using utilities provided by the vendor. The option does not back up
and recover these partitions.
When using machine-specific boot disks to perform a disaster recovery, the option
automatically partitions the machine hard disk into the original configuration.
This set of disks can only be used to perform a disaster recovery on this machine.
Starting Disaster Recovery Using the Bootable Disk Method
To perform disaster recovery on a computer using the bootable disk method,
perform the following steps:
1. Detach local tape devices, if any.
