Restore user and
application data
using the standard
Data Protector
restore procedure.
Critical volumes are restored.
Additional steps to perform
advanced recovery tasks are
required.
Boot the system
from the Windows
installation
medium and enter
the ASR mode.
Provide ASR
diskette.
Full client backup,
ASR diskettes with
an updated SRD
file and DP
binaries are
prepared.
See “Automated System Recovery” on page 85.
The following has to be completed before you can proceed to the next phase:
• Phase 0:
A full client backup and the IDB backup (Cell Manager only), must be performed,
and enough information must be collected by the administrator from the original
system to enable installation and configuration of the DR OS. An auxiliary boot
disk should be created for Disk Delivery Disaster Recovery on UNIX.
• Phase 1:
DR OS must be installed and configured and the original storage structure must
be re-established (all volumes are ready to be restored). The replacement disk for
Disk Delivery Disaster Recovery on UNIX must be made bootable.
• Phase 2:
Critical volumes are restored. Additional steps to perform advanced recovery
tasks are required. Refer to “Advanced recovery tasks” on page 96.
• Phase 3:
Check if application data is restored correctly (for example, databases are
consistent).
Manual disaster recovery method
This is a basic and very flexible disaster recovery method that involves recovering
the target system to the original system configuration.
First, you need to install and configure the DR OS. Then use Data Protector to restore
data (including the operating system files), replacing the operating system files with
the restored operating system files.
