Disaster

Jon William ToigoChairman, Data Management Institute2005

Any interruption in the normal access to a valid set of data used by applications and end users to execute mission critical business processes for an unacceptable period of time.

Could you survive a disaster?

• 25% of companies have a plan

• 60% of plans are never tested

The threat of data loss can’t be ignored

• Risks:

– High cost of data loss and downtime

– 70% of businesses fail after major data loss

• Needs:

– High availability and fast data recovery

– Recovery Time Objective (RTO) and Recovery Point Objective (RPO) close to zero

– Data recovery plans and procedures

The Challenge: Information Availability
