Current Situation ?
Not Good – Room for Improvement
Copyright©2015 Stormtime Ltd www.stormtime.co.uk
Better
Decrease (Minimise) MTTR(Mean Time to Recover)
(i.e. Reduce the size of the BLUE entries)
Copyright©2015 Stormtime Ltd www.stormtime.co.uk
Better Still
Increase (Maximise)MTBF
(Mean Time Between Failures)
(i.e. Reduce the number of RED entries)
Copyright©2015 Stormtime Ltd www.stormtime.co.uk
Best Solution, so Far !
Maximise MTBF and Minimise MTTR(i.e. Compare the first bar with the last bar)
“Cost” of “Loss of Service” ?

Service Level Agreement (SLA)
– Must be business led Quantifiable loss due to unplanned outages
eg Financial Cost , Credibility with Customers ?
All must be Identified & Quantified by Business Leaders
– Must be understood and accepted by IT
– Must include application availability tolerances
– Must take into account application performance thresholds
Copyright©2015 Stormtime Ltd www.stormtime.co.uk
• For all identifiable failures the DBA must know
– The options available for Recovery
– The complexity of the Recovery options
– The fastest option for Recovery
– How long the process will take
Recovery Time Objective (RTO)
Copyright©2015 Stormtime Ltd www.stormtime.co.uk
In the worst case scenario can :– Any committed data be lost ? (Incomplete Recovery)– If so – how much ?
Ten minutes ? An hour ? A day ? – Or is complete Database Recovery the only acceptable
situation
i.e. RPO is the actual Point of Failure
What does the SLA specify ?
Recovery Point Objective (RPO)
