CompTIA A+ Certification Core 2 (220-1102) - Backing Up Your Data in Windows

The video tutorial emphasizes the importance of regular backups to prevent data loss. It introduces different types of backups, including full, differential, and incremental, explaining their processes and benefits. The tutorial also covers backup strategies like the 321 rule and discusses backup options available in Windows 11, highlighting the need for multiple copies in different locations.

Why is it important to regularly schedule backups and set system restore points?

• To increase computer speed

• To prevent data loss

• To enhance graphics performance

• To improve internet connectivity

What is a major drawback of performing full backups every day?

• It improves system performance

• It takes a long time and adds overhead

• It requires no user intervention

• It is too cheap

What does a differential backup do?

• Backs up only system files

• Backs up changes since the last incremental backup

• Backs up changes since the last full backup

• Backs up all files every day

What is required to restore a system using incremental backups?

• Only the full backup

• The full backup and all incremental backups since then

• The last differential backup

• Only the last incremental backup

What does the 321 backup rule suggest?

• 3 copies of data, 2 different media, 1 offsite

• 3 types of media, 2 copies, 1 local

• 3 backups per day, 2 on-site, 1 in the cloud

• 3 cloud backups, 2 local backups, 1 tape backup

Why might optical media be a good choice for backups in certain environments?

• They are immune to magnetic fields

• They have the fastest read/write speeds

• They can survive underwater and in high humidity

• They are the cheapest option

What is a limitation of the backup options in Windows 11?

• It does not support cloud backups

• Users cannot choose what to back up

• Users have limited control over backup types

• It only supports full backups
