Disaster recovery

Question 1

Effects of Natural Disasters on Computers:

Answer 1

Power outages: Can lead to data loss or corruption if systems are not shut down properly.
Physical damage: Water, fire, or debris can damage hardware components, rendering them inoperable.
Data loss: Damage to storage devices or servers can result in data loss if proper backup measures are not in place.
Network disruptions: Infrastructure damage or connectivity issues can disrupt communication and access to network resources.

Question 2

Purpose and Characteristics of Disaster Recovery:

Answer 2

Purpose: To minimize the impact of disasters on business operations by ensuring continuity of critical systems and data.
Characteristics: Includes backup-restore procedures, offsite storage of backups, hot and cold spare hardware, and various site recovery options such as hot, warm, and cold sites.

Question 3

Difference Between Disaster Recovery and Business Continuity

Answer 3

Disaster recovery focuses on restoring IT systems and data after a disaster, while business continuity encompasses broader plans and strategies to ensure the organization can continue essential operations during and after a disaster.

Question 4

Designing a Disaster Recovery Plan

Answer 4

Involves identifying critical systems and data, establishing recovery objectives and priorities, defining procedures for backup and restoration, assigning responsibilities, and testing the plan regularly.

Question 5

Comparing Backup and Restoration Option

Answer 5

Options include full, incremental, or differential backups, as well as onsite and offsite storage, cloud backups, and data replication. Regular system backups are essential for data protection and recovery.

Question 6

Testing Disaster Recovery Plans

Answer 6

Essential to ensure the effectiveness of the plan against various disaster scenarios. Testing involves simulating disasters, executing recovery procedures, and evaluating the plan’s performance.

Question 7

Recovering Operating Systems

Answer 7

Involves boot methods like recovery console, Automated System Recovery (ASR), and Emergency Repair Disk (ERD) to recover from system failures or corruption.

Question 8

Using Server Operating System Features for Disaster Prevention and Recovery:

Answer 8

Leveraging built-in features like system restore points, shadow copies, and server backup utilities to prevent disasters and recover from them effectively.
