Final answer:
An incremental backup includes all data that has changed since the last full backup. This method saves resources and is essential for efficient data restoration.
Step-by-step explanation:
We call it a incremental backup when it is backed up with all the data that has changed since the last full backup. An incremental backup saves system resources by only backing up data that has changed since the last full or incremental backup. It is part of a robust data protection strategy, ensuring that in the event of data loss, the restoration process will be quicker since only the last full backup and subsequent incremental backups need to be restored. The subject of this question is Computers and Technology. Specifically, it is about data backups. When all the data that has changed since the last full backup is backed up, it is called an incremental backup. Incremental backups only add the changes made to the previous backup, making the process more efficient and quicker.
