Recovery
System Disaster
Recovery is an important component of the overall Business
Continuity Management Process and the plan that comes out of
it.
System Disaster
Recovery - analysis
Just as the analysis
of the business processes determine the priorities of the network,
applications, and systems, the same analysis should be applied to
your network design.
The individual
priorities sites and location of key services contribute to a fault
tolerant design, with resilience built into the network
infrastructure. Develop a recovery strategy to cover the
practicalities of dealing with a disaster.
System Disaster
Recovery - strategy
Such a strategy may be
applicable to several scenarios; keeping this in mind, the plan
should be assessed against each scenario to identify any actions
specific to different disaster types.
System Disaster
Recovery - plan
Your plan should
address the following: people, facilities, network services,
communication equipment, applications, clients and servers, support
and maintenance contracts, additional vendor services, lead-time of
Telco services, and environmental situations.
Your recovery strategy
should include the expected down time of services, action plans, and
escalation procedures. Your plan should also determine thresholds,
such as the minimum level at which can the business operate, the
systems that must have full functionality (all staff must have
access), and the systems that can be
minimized.
