Disk Delivery Disaster Recovery of an UNIX Client
Chapter 10 507
Disk Delivery Disaster Recovery of an UNIX
Client
To perform a Disk Delivery Disaster Recovery of a UNIX client, connect a
bootable disk that contains a minimal OS installation and Data
Protector Disk Agent to the crashed system. The administrator has to
ensure (before the disaster) that enough data has been collected to
correctly format and partition the disk.
For details on supported operating systems, refer to the HP OpenView
Storage Data Protector Software Release Notes.
Limitations
• This description does not cover the recovery of a cluster environment.
Depending on the configuration of the cluster environment,
additional steps and modification to the environment are necessary.
• RAID is not supported.
• Auxiliary disk should be prepared on a system of the same hardware
class as the target system.
Preparation
Preparation for this disaster recovery method should be performed on
several levels: gathering the information for your backup specification,
preparing the disk, preparing your backup specification (pre-exec), and
executing the backup. All of these preparatory steps are necessary before
executing disaster recovery of the client.
Gathering
Information
This section provides a list of items that need to be executed for each
target system at backup time, in order to perform successful disaster
recovery. If the information is collected as part of a pre-exec command, it
is important to document the location of these files in the Disaster
Recovery plan so that the information can be found once disaster strikes.
Also version administration (there is a collection of the “auxiliary
information” per backup) has to be considered.
