Three Components of Business Continuity
Fault-tolerant, failure-resistant
streamlined infrastructure
with affordable cost
foundation
1. High Availability
Non-disruptive backups and
system maintenance coupled with
continuous availability of
applications
2. Continuous Operations
Protection against unplanned
outages such as disasters
through reliable, predictable
recovery
3. Disaster Recovery
IT Data
Protection

5
Some Fundamental Truths about Business Continuity
1. Disasters Happen.
2. A Disaster is any incident or event that
interrupts access from decision-
makers and applications to business
data for whatever constitutes an
unacceptable period of time.
3. A Disaster is usually distinguished from
a mere inconvenience (temporary
crisis) by its duration.
4. The nature of the business process
impacted determine its tolerance for
downtime, which is relative and
contextual.

6
Business Continuity – Key Goals
1. Operations continue after a
disaster
2. Recovery is Predictable and
Reliable
3. Costs are Predictable and
Manageable
4. Protection of Critical Business Data
throughout the entire process

7
All Disaster Recoveries Follow “Bottom-Up” Approach

11
Planning Should Focus on Effects – Not Causes
All effects tend to fall into one of four categories
1. Workforce shortage caused by
infectious outbreak, labor strike,
extreme weather or a breakdown
in transportation
2. Loss of technology due to
cyber attack, interruption in
communications, power outage
or flood
3. Loss of facilities resulting from
fire, workplace violence,
hurricanes, floods and other
natural disasters
4. Failure in the supply chain that
prevents the shipping and
receiving of products and raw
materials

Business Continuity Plans (BCP) should
focus on “Business Process” as unit of
recovery
• Prioritize Gold, Silver, Bronze
• Decide RTO for each, for example:
• Gold in 4 hours
• Silver in 48 hours
• Bronze 2 weeks or longer
• Be pragmatic
Determine which Applications and Data
are required to support each Business
Process
• IBM Tivoli Application Dependency
Discovery Manager (TADDM)
Identify server, storage and network
infrastructure needed to support the
Applications and Data
• Can these run in the Cloud?

Consider adding IBM Cloud or leverage existing datacenter locations to
provide a broader distribution of data for higher availability and scalability
Server farm
Server farm
Modern applications often
required both structured (DB)
and unstructured data
Consider object storage
for unstructured data
In the event of a disaster,
secondary databases are up-
to-date… and unstructured
data readily accessible without
fail-over or data recovery

Sync versus Async
29
•Write to primary volume
•The primary site initiates an I/O to the
secondary site to transfer the data
•Secondary indicates to the primary
that the write is complete
•Primary acknowledges to the host
application that the write is complete
•Round-trip latency added to each
Write I/O
• 1 msec delay per 100km
separation distance
•Write to primary volume
•The primary site acknowledges to the host
application that the write is complete
Some later time:
•The primary site initiates an I/O to the secondary
site to transfer the data
•Secondary indicates to the primary that the write is
complete
•Primary and secondary bitmap updated that data is
in sync

Replication and Mirroring Consistency
• A mirror or backup copy is only useful if all data for an application is saved at a consistent
point
• To achieve snapshot consistency, Long Busy is used to create point in time copy on
multiple volumes at a single point in time
• To achieve consistency at a remote mirror location, the order of dependent writes must be
maintained and a dependent write to a volume must be mirrored if other dependent writes
were successfully mirrored
• The remote mirror functions each maintain consistency in their own way

Simplify and automate complex replication tasks
– Automated replication configuration scales up to thousands
of pairs of disk volumes
– Preserves historic configuration information
• easy setup for repetitive configuration or re-configuration
– Operational control of replication environment via a highly
usable GUI rather than DSCLI scripts or TSO commands
• but provides also CLI, csmcli
