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.

• 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
