Enhanced Automated Disaster Recovery of a
Windows System
Enhanced Automated Disaster Recovery (EADR) is a fully automated
Data Protector recovery method for Windows clients and Cell Manager,
where user intervention is reduced to minimum. For details on supported
operating systems, refer to the HP OpenView Storage Data Protector
Software Release Notes.
The EADR procedure for Windows platforms collects all relevant
environment data automatically at backup time. During configuration
backup, data required for temporary DR OS setup and configuration is
packed in a single large DR OS image file and stored on the backup
tape (and optionally on Cell Manager) for each backed up client in the
cell.
In addition to this image file, a Phase 1 startup information (stored in
the P1S file), required for correct formatting and partitioning of the disk
is stored on the Cell Manager. When a disaster occurs, EADR Wizard is
used to restore the DR OS image from the backup medium (if it has not
been saved on the Cell Manager during the full backup) and convert it to
a disaster recovery CD ISO image. CD ISO image can then be burned
on a CD using any burning tool and used to boot the target system.
Data Protector then automatically installs and configures DR OS,
formats and partitions the disks and finally recovers the original system
with Data Protector as it was at the time of backup.
IMPORTANT You have to perform a new backup and prepare a new DR CD after each
hardware, software or configuration change. This also applies to any
network configuration changes, such as change of IP address or DNS
server.
The recovered volumes are:
• the boot partition
• the system partition
• the partitions containing Data Protector
