Disaster Recovery Using Disk Delivery; One Button Disaster Recovery (Obdr) - HP Data Protector A.06.11 Recovery Manual

With manual recovery, it is important to collect the information regarding the storage
structure, which is not kept in flat files (such as partition information, disk mirroring,
and striping).

Disaster recovery using disk delivery

This method is supported on Windows and UNIX clients.
On Windows clients, the disk of the affected system (or the replacement disk for the
physically damaged disk) is temporarily connected to a hosting system. After being
restored, it can be connected to the faulty system and booted.
On UNIX systems, the auxiliary disk with a minimal operating system, networking,
and Data Protector agent installed is used to perform Disk Delivery Disaster Recovery.
This is a fast and simple method to recover clients. On Windows systems, the
operating system state is restored automatically as well.
TIP:
This method is especially useful with hot swap hard disk drives, because you can
disconnect a hard disk drive from a system and connect a new one while the power is
still on and the system is operating.

One Button Disaster Recovery (OBDR)

One Button Disaster Recovery (OBDR) is an automated Data Protector recovery method
for Windows clients and Cell Manager, where user intervention is reduced to a
minimum.
It collects all relevant Windows environment data automatically at backup time.
During a full 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, an OBDR device (a backup device, capable of emulating a CD-ROM)
is used to boot the target system directly from the tape that 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.
