The correct answer is A. Full (Backup). The description accurately defines a full backup, which copies all selected data, making restoration simple due to all files being in one media set. However, this method can lead to excessive storage requirements for files that do not change frequently.
Question
A full backup captures all files on the disk or within the folder selected for backup. Because all backed-up files are recorded to a single media or media set, locating a particular file or group of files is simple. In addition, full backups of files that do not change frequently (such as system files) could lead to excessive, unnecessary media storage requirements. Response:

Why each option
The description accurately defines a full backup, which copies all selected data, making restoration simple due to all files being in one media set. However, this method can lead to excessive storage requirements for files that do not change frequently.
A full backup captures all files on the disk or within the specified folders, regardless of whether they have changed since the last backup. This method simplifies restoration because all backed-up files are consolidated on a single media or media set, but it can be storage-intensive for data that rarely changes.
A differential backup copies only the data that has changed since the last *full* backup, not all files on the disk or within the selected folder.
An incremental backup copies only the data that has changed since the last *any type* of backup (full or incremental), not all files on the disk.
Data backup is a general term for the process of backing up data and does not describe a specific backup type with the outlined characteristics.
