3.      What is the major function of backup?

Answer: To be able to recovery data to a point in time

• A backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event
• Backup includes software to copy, move and track data, and hardware devices to store data. In addition, data backup devices can be in a public cloud.

4.      Which of the following describes a “backup window”?

• Backup window is a predetermined amount of time in which specific data must be restored to avoid any negative or damaging effects on the systems or applications that use the data.

5.      What kind of backup backs up data over the SAN without data passing through the app server?

Answer: Serverless backup

• Serverless backups is a data backup process that saves data and files without the use of a computer server.
• Commonly referred as a server-free backup, serverless backup eliminates the need for physical storage capacity. This means that the days of restoring server towers are vanishing.
