Bootable Devices; Important Guidelines; Media; Replacing Hardware - HP BB118BV - StorageWorks Data Protector Express Package User's Manual & Technical Reference

To perform disaster recovery on Machine2, you must purchase and install the disaster recovery option
on the second machine. If you wish to boot from tape, you require either a Media Sever license or a
separate tape drive with its own bundled software.

Bootable devices

Backup devices that support bootable media and bare-metal recovery include ...
• removable cartridge disk drives and
• tape drives that support One-Button Disaster Recovery.
Your computer must be able to boot from a device before it can be used for disaster recovery. Please
refer to the computer manufacturer's documentation on how to boot from a removable device.
One-Button Disaster Recovery (OBDR) is a firmware feature that is supported on some tape drives which
enables the tape drive to act like a bootable CD-ROM when it is put into Disaster Recovery mode. When
you create a full backup on an OBDR tape drive, Data Protector Express product automatically makes the
media bootable. When you run One-Button Disaster Recovery, (normally by a combination of power
cycling with the Eject button held down), your tape drive goes into a special Disaster Recovery mode that
enables it to restore your operating system and reboot from the most recent backup cartridge.
With bootable devices, you only need the device and the last full backup media for Disaster Recovery.
The whole backup can often be run from a single piece of media, making the restore much simpler to run.
All drivers for the bootable device are configured and loaded from the bootable media With a CD or DVD
you usually need multiple CD/DVDs, because the full backups are too big for a single piece of media.
The bootable device must be attached to the system at the time when the full backup is created for Data
Protector Express to make the media bootable. If you create the backup on a non-bootable device, you
cannot make the media bootable later in the same way that you can create a bootable CD or DVD
from the Data Protector Express wizard.

Important guidelines

Media

The Data Protector Express disaster recovery agent can be prepared using CD or DVD media and other
devices, depending on your computer configuration. To make your disaster recovery process as easy
as possible, please note the following:
• Data Protector Express rewrites most system configuration information to the media each time it
overwrites the media during backup jobs. Therefore, when making a full backup to be used for
disaster recovery, you should select Overwrite all media on the backup job's Options page.
• Recovering from a disaster works best with full backups, in which all disks on your system fit on
a single media. If the total amount of data on your system requires more than one media, Data
Protector Express will prompt you to change media during recovery. You can also use incremental
and differential jobs for recovery purposes, but you must insert the recovery media in the correct
chronological order.
• If you have a library, make sure the most recent backup media is loaded in slot 1. For more
information, see

Replacing hardware

Data Protector Express assumes that major changes to your hardware have not occurred. The hardware
on the target system must be nearly identical to the source system with the following exceptions:
• You may change your video adapter as long as the new video adapter is VGA compatible.
