Introduction
Chapter 10 439
What Is a
Computer
Disaster?
A computer disaster refers to any event that renders a computer
system unbootable, whether due to human error, hardware or software
failure, virus, natural disaster, etc. In these cases it is most likely that
the boot or system partition of the system is not available and the
environment needs to be recovered before the standard restore operation
can begin. This includes repartitioning and/or reformatting the boot
partition and recovery of the operating system with all the configuration
information that defines the environment. This has to be completed in
order to recover other user data.
What Is an Original
System?
Original system refers to the system configuration backed up by Data
Protector before a computer disaster hit the system.
What Is a Target
System?
Target system refers to the system after the computer disaster has
occurred. The target system is typically in a non-bootable state and the
goal of Data Protector disaster recovery is to restore this system to the
original system configuration. The difference between the crashed and
the target system is that the target system has all faulty hardware
replaced.
What Are Boot and
System
Disks/Partitions/
Volumes?
A boot disk/partition/volume refers to the disk/partition/volume that
contains the files required for the initial step of the boot process, whereas
the system disk/partition/volume refers to the disk/partition/volume
that contains the operating system files.
NOTE Microsoft defines the boot partition as the partition that contains the
operating system files and the system partition as one that contains the
files required for the initial step of the boot process.
