Time Machine is the backup feature included with Mac OS. Time Machine makes hourly backups for the past 24 hours, daily backups for the past month and weekly backups for all other months. When your backup drive becomes full, the oldest backups are deleted to make room for new ones. (If you need to keep backups for a significant period of time, use a larger backup disk!)
So, let’s say you realize that you cleaned up your desktop and accidentally deleted a file. Here is how to restore that single file:
- Close all active applications.
- Open Time Machine by selecting the icon from the menu bar (upper right).
- Select “Enter Time Machine”. A cascading display of Finder windows will appear, with a time line appearing along the right hand side of the screen.
- Use the Up/Down arrows just to the right of the finder windows to navigate to the day/time from which you want to restore the file. If you don’t know the date which it last existed on your desktop click through the images until that file appears.
- Once you have located to file to restore, select the file, then select “Restore” at the bottom of the screen.
- The file will be restored to your desktop.
It’s simple and these same steps can be applied to restoring multiple files at a time.
