Disasters happen every day...its a fact!
• Disasters are inevitable and
costly so why are so many
unprepared?
• Effective organizations have:
–
–
–
–
management foresight
tested procedures
processes
back-up facilities
• Business Continuity
Planning (BCP)

Business Continuity Planning vs.
Disaster Recovery Planning
• Both are directed at recovery of operations
• Business Continuity Planning is directed at the recovery
and resumption of business activities across the entire
enterprise
• Disaster Recovery Planning is usually directed at the
recovery of information technology systems and
business applications, including corporate data
• BCP addresses Processes, People and Property

Business Continuity is Different
• Glass is half empty
– We are throwing technology at the problem
• Glass is half full
– We are properly automating in a systematic way
• Technology cannot be the complete answer
Business Continuity Themes
• Disaster recovery
– Plan for site or component outage that affects mission-critical applications
• Business recovery & resumption
– Address mission-critical business processing in case of site outage
– Plan workarounds in case of application outage
• Contingency planning
– External event forces change to the internal business process
• Crisis management
– Address the overall management of the event
– Build plans to protect employees
– Maintain confidence in government

Business Impact &
Risk Analysis
Obtain executive sponsorship
• Identify what the enterprise has at risk
• Which business processes are most critical
– Prioritize risk management and recovery investments
• Identify the enterprise’s vulnerability to risks so they
can be mitigated in the project design phase

Is this plan worth implementing?
• Develop recovery strategies and processes
• Create team responsible for the daily operation of
the processes create detailed plans and
procedures.
BCP Process
Phase 3:
Maintain
the plan
Plan MUST be tested and kept up to date
Test
Process
• Test the recovery process before implementation
to ensure that requirements can be met.
• Keep the plan current by initiating a review of
every change to business processes or systems.

Implement Your
Business Continuity Plan
• Determine what is relevant to your business
• Know what assets you have
– Data
• Where is it?
• How often is it used?
• Is it still relevant to the business?
– Systems, Networks and Storage
• What is running?
• Know asset exposures for Security
– Determine what threats affect each individual asset and know the risks of
these threats
• Who has access?
• How is it being accessed?
• When is it being accessed?
Implement Your
Business Continuity Plan
• Know what action to take and implement
– Utilize validated remediation and automatically deliver fixes to
vulnerable assets
• Measure status, progress and compliance
– Provide enterprise reporting to measure progress, summarize
risks and determine regulatory compliance
Implement all of these steps while performing
your everyday business tasks

BC/DR Must Address Every Component
• Network Infrastructure
• Data Storage – online, near-line and off-line
• Application servers and their offspring
Any component down = the entire system is un-usable
Network Infrastructure
• Wide Area Traffic Manager to direct client traffic to
proper site
• Network load balancer to distribute incoming requests
• Dedicated, fast link between sites
– Influences production database performance
• Redundant components and paths
– Network paths to the site and within the site
BC/DR Techniques for Data Storage
• Snapshots – frequent, within an array, FC, temporary
• Mirrors – frequent, in a different array, FC, temporary
• Replicas – synchronous or async, remote or local, FC
or IP, temporary or semi-permanent
• Near-Line Disk – infrequent, x-platform, FC or IP, BI
copy, DLM, or staging for backup
• Tape Backup – infrequent, FC or IP, required best
practice for DR
Application Availability with Local Clustering
Server 2
Instance ‘B’
Server 1
Instance ‘A’
Database
Protects from local server failures
Depends on shared available storage
Wide Area Clustering
• Extends local clustering model to several sites
• Requires data mirroring or replication

Key Steps to Success
•
•
•
•
•
•
Conduct a Business Impact Analysis
Identify which processes are truly critical and cost of BC
Prioritize investments in people and technology
Plan and Implement
Test, test, test!!!
Review the business continuity plan when the business
process changes
