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:
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.
Overview
The general steps using the One Button Disaster Recovery method for a Windows
client are:
1. Phase 0
a. You need an OBDR backup (create the backup specification using the Data
Protector One Button Disaster Recovery wizard).
b. If you are using encrypted backups, store the encryption key on a removable
medium so that it is available for disaster recovery. You will need the key
for a Cell Manager recovery or if the connection to the Cell Manager cannot
be established.
2. Phase 1
Boot from the recovery tape and select the scope of recovery.
