7. You need to cover all areas and ensure the level of protection is equal – your
weakest area is determining the total level of protection
How to protect your data?

• Is my database configured to reduce risk?
• Has my database drifted away from its approved configuration?
• Who are my highest-risk users?
• What are those users doing?
• What activities do I audit?
• How do I manage the audit trail?
• What types of sensitive data do I have?
• How much sensitive data do I have?
• Can I minimize the amount of sensitive data I’m responsible for?
• How is my DB infrastructure protected?
• How is the High Availability secured?
• What is a disaster recovery architecture and policy?
• Etc.
Protecting Data is Important

14. There is very well defined architecture and best practice how to do it.
Best option is to use Exadata – developed by Oracle to run Oracle DB

15. Data protection terminology
Recovery point and recovery time objectives
15 Copyright © 2020, Oracle and/or its affiliates |
Recovery Point Objective (RPO)
Tolerance for data loss (sec’s, hours, days); determines
frequency of backups and replication approaches
Recovery Time Objective (RTO)
The shorter the Recovery Time Objective (RTO) the
quicker you get back to business
Data Loss
(Recovery Point Objective)
Downtime

16. How to Protect Data and Systems from Outages
Planned and unplanned
16
High Availability
• Protect from localized failures (servers,
bugs, …)
• Local redundancy
Disaster Recovery
• Protect from site failure (entire data
center)
• Site redundancy
Copyright © 2020, Oracle and/or its affiliates |

17. • Highest availability
- Auto, fast failover to running instance(s)
- Zero-downtime rolling upgrades
• Highest ROI
- All instances active (no idle resources)
- Applications run unchanged
• Scalability-on-demand
- Add, change capacity online
- Ideal for database consolidation
• Fleet patching and maintenance
High Availability (HA)
Localized protection with Oracle Real Application Clusters (RAC)
17 Copyright © 2020, Oracle and/or its affiliates |

18. • Basic DR (included with DB EE)
- License primary and secondary sites
• Active-passive
- Standby is used only for failovers
• Automatic failover to Standby site
• Zero / near-zero data loss
• Continuous data validation
• Simple migrations and upgrades
Disaster Recovery (DR)
Site failover with Oracle Data Guard (DG)

19. • Advanced DR
• Active-active*
- Queries, reports, backups
- Occasional updates (19c)
- Assurance of knowing system is operational
• Automatic corruption repair
• Rolling upgrades
• Application continuity
• Zero data loss across any distance

• Active-active
- Full, multi-master, bi-directional replication
- Full read-write access
• Heterogeneous
• Zero downtime DB maintenance and
platform migration
• Assurance of knowing system is
operational

Bronze Single instance + Backup Dev, test, prod.
Silver Bronze + HA clustering Prod. / departmental
Gold Silver + Disaster recovery Mission critical
Platinum Gold + Zero data loss and zero downtime Extreme critical
MAA

Topology Suitable databases
Addresses Service Level Agreements (SLA) for data loss and downtime
during planned and unplanned outages

22. Scale-out design based on proven Oracle Database technology
§ Database server resources scale by over 140X
§ Storage server resources scale by over 160X
Runs faster by moving the compute to the data
§ Much faster than all-flash arrays; not limited by SAN bandwidth
§ Requires owning the full stack; can’t be solved in storage alone
An Exadata X8M rack delivers 560 GB/sec to any server
High availability based on proven technologies and MAA best practices
Oracle Exadata X8M scale-out architecture
Performance and capacity scaling with no single point of failure

23. Traditional technologies for Backup & Restore are not keeping pace
with recent IT technologies development and as it is
« LAST MILE OF DEFENCE»
it requires new approach
