7. To add a Time Machine drop-down menu to the menu bar at the top of the
screen, select the Show the Time Machine status in the menu bar check
box. This menu enables you to start a backup, enter Time Machine to restore files,
or open the Time Machine Preferences screen.
Time Machine begins backing up your files, but the first backup may take some
time. Subsequent backups are faster because Time Machine only backs up new
or changed items. A status bar displays the progress of the backup.
Time Machine backs up your computer every hour and keeps the following
backup sets:
• Every hour for 24 hours
• Every day for the past month
• Weekly until the My Book drive is full.
If a backup is interrupted, for example, if the computer goes into sleep mode or
the My Book drive is disconnected, it will resume automatically once the
computer is available.
To see information such as available capacity and the date and time of the oldest,
latest, and next backup, select Open Time Machine Preferences on the Time
Machine drop-down menu:
