Leo is planning the new backup strategy for a subsidiary his company is purchasing that does not currently have a backup strategy in place. He decides that a full backup should be run once per week. Once per day, everything that has changed since the last full backup will be archived. Once per hour everything that has changed since the last backup of any type will be backed up. Which of the following describes the backups that will be run every hour? a. Differential
b. Variable
c. Incremental
d. Flexible

C. Incremental backup

Explanation:

An incremental backup is a type of backup where the succeeding copies of the data is made up of only those positions that have changed since the previous or prior copies were made. Such backups are desired since they limit the usage of space for storage and these types of back ups are faster to do that the differential backup.

When we bring this explanation to this question, we can easily see that the backup that is being carried out is done on everything that has changed since the last backup (previous backup). Therefore this is an incremental backup.
