UNIT 9
Week 9 of the course emphasizes the significance of Business Continuity (BC) and Disaster Recovery (DR), in managing and reducing risks. Business Continuity ensures that key business operations can persist during disturbances while Disaster Recovery is dedicated to recovering IT systems and data after events, like cyberattacks, natural disasters or system breakdowns. Important elements of business continuity and disaster recovery (BCDR) planning consist of. The Business Impact Assessment (BIA) is a process that pinpoints business operations and evaluates the consequences of any disruptions to them. Definition of Recovery Time Objective (RTO), as the time to recover systems following a breakdown. The Recovery Point Objective (abbreviated as RPO) indicates the level of loss of information. It is determined by the interval between backup operations. The course also covers developments in Information Risk Management like cloud-based backup solutions and enhancements in cybersecurity through automation technology. This shows how dealing with risks is becoming more complex, in today’s world and businesses need to plan ahead for recovery and business continuity measures.

These proficiencies play a role in safeguarding businesses’ capability to bounce back and manage adversities amidst changing and emergent hazards.
UNIT 10 TASK
DR Solution 1 with a Recovery Point Objective (RPO) of 1 hour and a Recovery Time Objective (RTO) of 8 hours while highlighting the need, for High Availability (HA). Definitions.
•RPO (Recovery Point Objective); The longest duration within which data loss, due to an event is deemed acceptable, is one hour, in this scenario.
•RTO (Recovery Time Objective); The acceptable timeframe, for systems to be up and run again following a disaster is, within 8 hours.
•High Availability (HA); Aims to keep the system running to maximize uptime and reduce downtime occurrences effectively through failover solutions that cause minimal disruptions.
Elements of Design.
Cloud storage, for purposes, with data duplication.
The instant or almost instant copying of information, from systems to backup systems (in the cloud or far away locations).
Make sure that the data stays current, and that any potential incident doesn't result in, then an hour’s worth of data loss.
• Balancing the load.
It spreads network traffic among servers or systems to maintain the applications responsiveness in case one server fails.
In systems (HA systems) load balancers play a crucial role, in avoiding service disruptions by automatically rerouting traffic to functioning systems.
• Backup Plan.
Automated switching to the system, in case of a problem being identified in the system.
During an emergency the system seamlessly transitions to an infrastructure such as the cloud to ensure operations with minimal downtime.
If there is a breakdown, in the systems operation occurs; it will switch over from the location to a secondary backup site within an 8 hour RTO automatically.
• We ensure that data loss is limited to an hour by replicating and storing snapshots in the cloud.
Effective Strategies.
Make sure to set up storage in locations to safeguard against disasters, in specific regions.
Make sure to implement automated disaster recovery testing to verify that a failure occurs as intended.
DR Solution 2 with a Recovery Point Objective (RPO) of 24 hours and a Recovery Time Objective (RTO) of 72 hours, without the need, for High Availability (HA).
Here are some explanations.
In the event of a disaster, it is possible to lose, up to 24 hours’ worth of data.
Reaching a recovery within 72 hours is essential; this indicates that immediate system restoration is not necessary.
Continuous up time is not essential as occasional downtime is acceptable long as the system's back up and running according to the Recovery Time Objective (RTO).
Elements of Design.
•Backup data to the cloud daily.
Data is stored in the cloud every day using services such as Amazon Storage, Microsoft Azure Blob Storage or Google Cloud Storage.
In the event of a disaster scenario arises at any moment, in the future; you can rest assured that the backup available will not be than 24 hours old, ensuring that important data is still preserved up, to date.
Backup Options Comparison.
No need for backup systems necessary.
Cold Backup refers to the process of keeping data and applications in a state until they are manually recovered following an incident.
A warm backup is a type of backup that requires some intervention and additional configuration to fully restore services.
•Procedure for recovery
Recovery can occur manually without the need for HA by performing tasks such, as system boot up and data restoration.
How It Operates.
Data is kept in cloud storage away, from the location and in case of any issue it is recovered manually using the recent backup from that day.
Noncritical business applications may not require attention allowing for a recovery period of, up to 72 hours.
Key Recommendations.
For conserving speeding up recovery options for both differential backups.
Make sure to conduct tests to verify that the backups function properly and that recovery protocols are established as a measure.
DR solution 2 with a Recovery Point Objective of 5 minutes and a Recovery Time Objective of 1 hour. High Availability is necessary for this solution.
Definitions.
• With a Recovery Point Objective (RPO) of 5 minutes there is a limit on the amount of data that can be lost requiring continuous data replication to ensure minimal loss.
• If there is an issue it needs to be fixed and up and running again within an hour.
Ensuring accessibility is crucial, for High Availability (HA) where the system must remain operational without prolonged downtime.
Components of Design.
• Instant Data Duplication.
Continuous replication of data to a location guarantees that the loss of data is minimally capped at 5 minutes.
To maintain data integrity, between backup systems synchronous replication is a utilized method. Backup mechanisms.
A complete duplicate setup (comprising servers, networks and storage) spread across areas.
Involve active passive groups where both sites can manage traffic (active active) or the secondary site is ready, as a backup (active passive).
• Automated system backup, in case of failure.
An automated system identifies any issues. Promptly switches the service to the backup infrastructure ensuring minimal to no interruption.
Failover occurs within a timeframe of seconds, to minute. Ensure that all services are fully operational before the 1-hour Recovery Time Objective (RTO) expires.
• Disaster Recovery, as a Service often abbreviated as DRaaS;
Cloud services provide managed services such as real time replication and failover options (, for instance AWS Elastic Disaster Recovery and Azure Site Recovery).
In case the main system encounters issues or malfunctions, the cloud is ready to assume control without delay.
How the process functions.
In case of a crisis situation arises, live duplication guarantees that 5 minutes of data is forfeited, and the failover process occurs spontaneously in just a matter of seconds to reduce any downtime issues effectively.
• The entire system is restored within a time frame of than an hour, which makes it ideal, for applications, to missions.
Guidelines for Success.
Use data centers located in parts of the world to reduce the chances of outages happening in one region.
