Assume you are a security professional. You are determining which of the following backup strategies will provide the best protection against data loss, whether from disk failure or natural disaster:
- Daily full server backups with hourly incremental backups
- Redundant array of independent disks (RAID) with periodic full backups
- Replicated databases and folders on high-availability alternate servers
Answer the following question(s):
- Which backup strategy would you adopt? Why?

Introduction
You are a security professional and have been tasked with making a recommendation on which backup strategy provides the best protection against data loss. Your boss wants to know if you can make an informed decision based on your knowledge of backup technologies, as well as the availability of resources like tape drives and servers.
a. Periodic backup of all data to CD media
Periodic backup of all data to CD media.
This strategy provides great protection against disk failure, but it’s not a good choice for off-site storage or disaster recovery because the data is stored on individual CDs and are subject to loss if they are not protected.
b. On-site tape backup
Tape backup is a good solution for protecting data against natural disaster. It’s the only option that protects against natural disaster, works for off-site backup, and works for periodic backup as well.
c. Off-site tape backup
Off-site tape backup is the only option that protects against natural disasters, data loss, and both.
You should use an off-site tape backup since that is the only option that protects against natural disasters and data loss. (You may have to explain why other answers are incorrect.)

A periodic backup is not a good option because it does not provide any protection against disaster, theft or loss of power. If your company has sensitive information on its computers, you should also consider using encryption software on them as well as encrypting all video surveillance footage before storing it in the cloud so that hackers cannot access it easily if they gain access to your network or server room. Also, if you want a backup solution with higher levels of security than just encrypting files on disk drives alone provides then external hard drives would be needed too!
The best way for companies with sensitive data about their customers’ medical records or financial details (e.g., credit card numbers) would be by using separate physical copies stored away from mainframe servers where hackers could steal them easily without having direct access
Conclusion
Now that you have a better understanding of what backup strategies are available and how they work, it’s time to decide which one is best for your business. While on-site tape backups offer great protection against data loss, they are expensive and vulnerable to natural disasters such as earthquakes or fires. Off-site tape backups have been shown to reduce recovery times by more than 50% when compared with traditional disk backup solutions. Another benefit is that off-site tape backups can be easily moved from location to location if needed in order
