Introduction
Chapter 10442
The Recovery
Process
The disaster recovery process consists of 4 phases with the Phase 0
(preparation) being the prerequisite for a successful disaster recovery. In
Phase 1, DR OS is installed and configured, which usually includes
repartitioning and reformatting of the boot partition, since the boot or
system partition of the system are not always available and the
environment needs to be recovered before normal restore operations can
resume. Operating system with all the configuration information that
defines the environment with Data Protector (as it was) is restored in
Phase 2. Only after this step is completed, is the restore of applications
and user data possible (Phase 3). A well-defined, step-by-step process has
to be followed to ensure fast and efficient restore.
