What defines a daily incremental backup?

A daily incremental backup is characterized by its focus on efficiency and resource management. It specifically captures only the new or altered data that has occurred since the last full backup or the last incremental backup. This approach helps in reducing the amount of storage space used and speeds up the backup process since it does not duplicate data that has already been backed up.

By only including the changes made to the data, incremental backups can be completed quickly, allowing for more frequent backups without overwhelming system resources. This method is particularly useful for organizations that need to maintain up-to-date backups without incurring the time and storage costs associated with full backups every day.

In contrast, other options describe different types of backups, such as full backups, which include all files, or specific targeted backups, which may not encompass all changes since the last full backup. Thus, the most accurate definition of a daily incremental backup is one that focuses on capturing only the new or modified data since the last backup event, whether that be full or incremental.
