Explanation

A full backup copies all selected data every time it runs, regardless of whether files have changed since the last backup. Because it captures everything, it requires the most time and storage space, making it impractical for daily runs in most environments. However, it creates a complete, self-contained snapshot, which is why it is used to establish archive or baseline tape sets-a known-good, comprehensive copy of the system at a specific point in time. Full backups are typically scheduled weekly or monthly, run during off-peak windows when storage capacity and time are available. (B) Incremental backups only capture changes since the last backup of any type, minimizing time and space. (C) Differential backups capture changes since the last full backup. (D) 'Tape backup' is a storage medium, not a backup method.
