What type of backup saves only the most recent changes to an existing backup file? Choose the answer.
Question 19 options:
differential backup
full backup
incremental backup
partial backup
incremental backup
The type of backup that saves only the most recent changes to an existing backup file is called an incremental backup.
The type of backup that saves only the most recent changes to an existing backup file is called an "incremental backup." To understand this concept, let's break it down:
Incremental Backup: An incremental backup only copies the data that has changed since the last backup, regardless of whether the previous backup was a full backup or an incremental backup itself. It identifies and saves only the new or modified data since the last backup, reducing the time and storage space required for backup.
Differential Backup: A differential backup, on the other hand, copies all the data that has changed since the last full backup. It includes all the changes made since the last full backup rather than just the most recent changes.
Full Backup: A full backup copies all the data from a system or specific files and folders. It creates a complete copy of everything selected for backup and is typically performed initially or periodically to have a baseline to restore from.
Partial Backup: There is no specific backup type called a "partial backup." It might refer to backing up only specific parts or files of a system, but it is not an established backup strategy on its own.
Based on these explanations, the correct option for the type of backup that saves only the most recent changes to an existing backup file is an "incremental backup."
