One Button Disaster Recovery of a Windows
System
One Button Disaster Recovery (OBDR)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.
OBDR collects all relevant environment data automatically at backup
time. During backup, data required for temporary DR OS setup and
configuration is packed in a single large OBDR image file and stored on
the backup tape. When a disaster occurs, OBDR device (backup device,
capable of emulating CD-ROM) is used to boot the target system directly
from the tape which contains the OBDR image file with disaster recovery
information.
Data Protector then installs and configures the disaster recovery
operating system (DR OS), formats and partitions the disks and finally
restores the original operating system with Data Protector as it was at
the time of backup.
IMPORTANT You have to perform a new backup 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
Any remaining partitions can be recovered using the standard Data
Protector recovery procedure.
