Using and Configuring Time Machine✯

How Time Machine Works:✯

On first use, a complete backup of your internal hard drive will be performed. This may take between 30 minutes and 1 hour depending on the data stored on your disk.

Once completed, Time Machine is configured to perform backups:

  • Every hour for the past 24 hours
  • Daily for the past month
  • Weekly until the disk is full (after which it will delete the oldest backups)

Time Machine only backs up changes made to your data.

Where to Find Time Machine:✯

  • In the Applications folder
  • In System Preferences
  • In your menu bar (if the option was enabled)
