Backup and Data Protection Concepts

Why is it crucial to have a backup of your data?

• To reduce electricity usage

• To improve computer speed

• To recover data easily and quickly

• To increase storage space

What is a key advantage of onsite backups?

• They do not need any software

• They are more secure than offsite backups

• They are less expensive and data is immediately available

• They require less storage space

What is a potential risk of offsite backups?

• They are slower to restore than onsite backups

• They require no internet connection

• They can be accessed by unauthorized parties if not encrypted

• They are always more expensive

What should be considered when choosing backup software?

• Whether it can delete old files automatically

• If it can increase computer speed

• If it is built into the operating system or from a third party

• Whether it is free

Why is encryption important for cloud-stored backups?

• To increase upload speed

• To ensure data is unreadable by unauthorized parties

• To reduce storage costs

• To make data sharing easier

How often should backups be tested to ensure data can be restored?

• Only when a disaster occurs

• Regularly, to ensure all methods work properly

• Once a year

• Never, if the backup is automated

What is a snapshot in the context of virtual machines?

• A full backup of the entire system

• A quick backup method that captures the state of a VM

• A method to increase VM performance

• A way to delete unnecessary data

What is a common strategy for using snapshots?

• Taking a snapshot only when needed

• Taking a snapshot every 24 hours

• Taking a snapshot every hour

• Taking a snapshot once a month

What is the main benefit of using replication for backups?

• It is cheaper than other backup methods

• It provides real-time data updates across multiple locations

• It requires no internet connection

• It reduces the need for physical storage

How does journaling help prevent data corruption?

• By reducing the amount of data written

• By encrypting all data

• By writing data to a journal before the final version

• By storing data in multiple locations
