Introduction

Short Demonstrations :Simple ‘Cold’ (Consistent) Backup

‘Hot’ (Inconsistent) Incremental Backup

The Course Topics


Current Situation ?

Not Good – Room for Improvement


Better

Decrease (Minimise) MTTR(Mean Time to Recover)

(i.e. Reduce the size of the BLUE entries)


Better Still

Increase (Maximise)MTBF

(Mean Time Between Failures)

(i.e. Reduce the number of RED entries)


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


• 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)


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)


The

Backup Strategy

must meet the requirements of the

Recovery Strategy

which must meet the requirements of the

Service Level Agreement
