tmutil

tmutil is a command line tool available on macOS systems that provides various functionalities related to Time Machine, the built-in backup software. It allows users to interact with and manage Time Machine backup processes directly from the Terminal. With tmutil, users can perform tasks such as enabling or disabling Time Machine backup, starting or stopping backups manually, and even restoring files from backups. It also provides options to perform backups of specific folders or exclude certain files from being backed up. tmutil can display information regarding the status of backups, including the size of backups, the estimated time remaining for a backup, and the last backup date and time. Additionally, tmutil can be used to list the available snapshots on a system, which essentially allows users to revert their system to a specific point in time.
