Time Machine is designed to efficiently back up important data while avoiding files that may not need to be preserved, such as temporary files and cache. These types of files are often unnecessary for recovery purposes because they are typically transient and can be recreated easily by the operating system or applications.

Temporary files are created during the use of applications and can include things like incomplete downloads or files associated with applications while they are running. Cache files, on the other hand, are used to speed up processes and are regularly updated. Including such files in backups would not only consume unnecessary storage space, but could also complicate the restoration process since these files can often be regenerated.

By default, Time Machine specifically excludes system files that are not essential for user data recovery or are transient in nature, reinforcing its focus on user files and critical system information that contribute to a stable and functional environment. This prioritization ensures that backups are efficient and relevant, allowing users to restore their systems without unnecessary bloat.
