Teresa Ruiz works as a cloud security engineer in an IT company. In January 2021, the data deployed by her in the cloud environment was corrupted, which caused a tremendous loss to her organization. Therefore, her organization changed its cloud service provider. After deploying the workload and data in the new service provider's cloud environment, Teresa backed up the entire data of her organization. A new employee, Barbara Houston, who recently joined Teresa's organization as a cloud security engineer, only backed up those files that changed since the last executed backup. Which type of backup was performed by Barbara in the cloud?

D.
Differential Backup
Suggested answer: C

Explanation:

An incremental backup involves backing up only those files that have changed since the last backup of any type (full or incremental). This approach saves time and storage space compared to full backups by only copying data that has changed.

1.Incremental Backup Process: After a full backup is taken, subsequent incremental backups only include changes made since the last backup.

1.Efficiency: This method is efficient in terms of both time and storage, as it avoids duplicating unchanged data.

1.Comparison with Other Backups: Unlike differential backups, which copy all changes since the last full backup, incremental backups only include the changes since the last backup of any kind.
