What is ITIL and how does it relate to IT troubleshooting?

ITIL is a framework for operating an IT department, covering service management, operations management, and more. It provides a structured approach to IT service management, which is essential for effective troubleshooting.

Why is gathering detailed information important for troubleshooting?

Gathering as much information as possible is crucial for effective troubleshooting. It helps in identifying the root cause of the issue and finding the most appropriate solution.

How can fault tolerance be achieved in IT systems?

Fault tolerance can be achieved by making components redundant, utilizing clustering, and implementing backup and recovery strategies to ensure minimal impact in case of system failure.

What are the different types of backups and their advantages?

Differential backups are slower to back up but faster to restore, while incremental backups are faster to back up but slower to restore. Each type has its own advantages and should be chosen based on specific requirements.

Why is it important to isolate data from applications when planning backups?

Isolating data from applications ensures that critical data is protected and can be restored independently of the applications. This helps in maintaining data integrity and availability during system recovery.
