Taylor has configured a backup that will backup all of the changes to a system since the last time that a full backup occurred. What type of backup has she set up?

Differential backups backup all of the changes since the last full backup. An incremental backup backs up all changes since the last incremental backup. A snapshot captures the machine state and the full drive at a bitwise level, and full backups are a complete copy of a system but typically don’t include the memory state.
