In this way, Time Machine can maintain extensive snapshots of your system over time. This routine should ensure that even with a relatively small backup drive (at least the size of the collective data you are backing up), you will have ample system restore points and access to prior versions of files. These local snapshots are stored on your Mac’s startup partition along with all your other files.Apple's Time Machine feature is a full-system backup routine that will maintain hourly backups for the past day, daily backups for the past week, and weekly backups for as long as there is space in the drive to store them, and uses a feature called "hard linking" to share unchanged data of previous backup files with new files copied to the backups. Your Mac automatically creates them in the background, and the Time Machine icon on your menu bar won’t even say it’s doing anything as it does so. These snapshots are designed to help you recover deleted files or previous versions of files, even if your laptop is away from its Time Machine drive for a while.
If you’re using a desktop Mac with Time Machine enabled, or if you’re using a Mac notebook with Time Machine disabled, your Mac won’t bother creating local snapshots. Second, you must have enabled Time Machine to back up to an external drive. First, you must be using a Mac notebook and not a Mac desktop PC. Local snapshots are only created if two things are true.
