Backing Up and Retrieving Files with Time Machine

If you’ve deleted files and emptied the Trash or if your hard disk crashes or corrupts your files, your data may be gone for good unless you’ve been using Time Machine. To use Time Machine, you first need to connect an external hard disk (or Apple’s Time Capsule) to your Macintosh and then set up Time Machine. As you use your Macintosh, Time Machine backs up your files hourly, daily, and weekly. The number of backups that Time Machine can save depends on the amount of space available on your external hard disk.

Before you can use Time Machine, you must set it up. After that, Time Machine will start backing up your files automatically. You won’t have to do a thing.
