Figure 10-9: Business Continuity Planning
Business Continuity Planning
A business continuity plan specifies how a company plans to restore core business operations when disasters occur
2
Figure 10-9: Business Continuity Planning
Business Process and Analysis
Identification of business processes and their interrelationships
Prioritizations of business processes Downtime tolerance (in the extreme, mean time
to belly-up)
Resource needs (must be shifted during crises)

Figure 10-9: Business Continuity Planning
Communicating, Testing, and Updating the Plan Testing (usually through walkthroughs) needed to
find weaknesses
Updated frequently because business conditions change and businesses reorganize constantly Telephone numbers and contact numbers must
be updated even more frequently than the plan as a whole

Business Continuity Planning A business continuity plan specifies how a
company plans to restore core business operations when disasters occur
Disaster Recovery Disaster recovery looks specifically at the technical
aspects of how a company can get back into operation using backup facilities
5
Figure 10-10: Disaster Recovery
Types of Backup Facilities Hot sites
Ready to run (power, HVAC, computers): Just add data
Considerations: Rapid readiness versus high cost
6
Figure 10-10: Disaster Recovery
Types of Backup Facilities
Cold sites
Building facilities, power, HVAC, communication to outside world only
No computer equipment
Might require too long to get operating
7
Figure 10-10: Disaster Recovery
Types of Backup Facilities
Site sharing
Site sharing with a firm’s sites (problem of equipment compatibility and data synchronization)
Site sharing across firms (potential problem of prioritization, sensitive actions)

Figure 10-10: Disaster Recovery
Types of Backup Facilities
Hosting
Hosting company runs production server at its site
Will continue production server operation if user firm’s site fails
If hosting site goes down, there have to be contingencies

Restoration of Data and Programs
Restoration from backup tapes: Need backup tapes at the remote recovery site
Real-time journaling (copying each transaction in real time)
Database replication

Testing the Disaster Recovery Plan
The importance of testing: Find problems, work faster
Walkthroughs Go through steps in real time as group but do
not take technical actions Fairly realistic Unable to catch subtle problems
