Data Security and Backup Concepts

This video tutorial covers various methods to prevent data loss, including RAID systems, master-slave backups, sharding, failover systems, encryption techniques, offsite and cloud storage, and removable media. Each method is explained with its applications and benefits for individuals and businesses. The video also credits Cosmo Wilson for the PowerPoint used in the screencast.

What does RAID stand for in data loss prevention?

• Redundant Access of Integrated Disks

• Reliable Array of Integrated Disks

• Random Access of Independent Disks

• Redundant Array of Independent Disks

Which RAID level involves mirroring data to both drives?

• RAID 5

• RAID 0

• RAID 6

• RAID 1

In a master-slave backup system, what happens when the master server is down?

• The slave servers take over

• Data is lost permanently

• The system automatically repairs

• The system stops functioning

What is the purpose of sharding in data security?

• To mirror data across multiple drives

• To break files into smaller fragments for security

• To encrypt data with a public key

• To increase data storage capacity

What is a failover system designed to do?

• Automatically start backup hardware when an error occurs

• Encrypt data using symmetric keys

• Store data offsite for security

• Mirror data across multiple servers

Which type of encryption uses the same key for both encryption and decryption?

• Private key encryption

• Symmetric encryption

• Asymmetric encryption

• Public key encryption

What is a key advantage of cloud storage?

• It is only accessible offline

• It requires no internet connection

• It is accessible at all times with an internet connection

• It is only available to large businesses

What is offsite storage primarily used for?

• Mirroring data across multiple drives

• Encrypting data with a private key

• Providing a server with the latest backup

• Storing data on the same premises

Which of the following is considered removable media?

• RAID systems

• Offsite storage

• External hard drives

• Cloud storage

What is the concept of generation backups?

• Encrypting data with different keys

• Making a complete backup weekly and keeping multiple generations

• Storing data in the cloud

• Creating a backup every day
