Appendix
B
Recovering a Cluster
Disaster recovery in a Windows-based cluster environment is a complex task.
Although BrightStor ARCserve Backup makes it easier to recover your
mission-critical cluster environment, it still requires some planning and effort. It is
important that you understand the concepts described in this guide, and test the
scenarios suitable for your specific environment.
A server cluster is a group of independent servers running cluster services and
working collectively as a single system. Server clusters provide high-availability,
scalability, and manageability for resources and applications by grouping multiple
servers running Windows 2000 Advanced Server.
This appendix provides information about recovering the cluster-shared disks,
failed cluster nodes, or the entire cluster quickly, with minimum interruption to
the service.
Requirements
The following sections detail the requirements for BrightStor ARCserve Backup
Disaster Recovery Option to recover a cluster.
Software Requirements
■
Microsoft Windows 2000 Advanced Server or Microsoft Windows 2003 Server
installed on all computers in the cluster
■
A name resolution method. For example, Domain Naming System (DNS),
Windows Internet Naming System (WINS), or HOSTS.
■
A Terminal Server for administering remote clusters.
■
BrightStor ARCserve Backup Disaster Recovery Option on cluster nodes
needing protection if backup devices such as tape devices or tape library
devices are attached to one or all cluster nodes. If no backup devices are
attached to the cluster setting, the BrightStor ARCserve Backup Client Agent
for Windows should be installed on all cluster nodes needing data protection.
