Time Machine está haciendo una copia de seguridad de los archivos de StdExclusions.plist

Por alguna razón, Time Machine está haciendo una copia de seguridad del contenido listado en /System/Library/CoreServices/backupd.bundle/Contents/Resources/StdExclusions.plist , lo cual no tiene sentido. Específicamente, las carpetas / private / var / y / private / var / db que cambian con frecuencia para que tengan una copia de seguridad de cada ejecución. Estoy en High Sierra.

Editar: para satisfacer la curiosidad de un comentario, aquí está el archivo en cuestión.
