Time Machine is the breakthrough automatic backup that’s built right into Mac OS X. It keeps an up-to-date copy of everything on your Mac — digital photos, music, movies, TV shows, and documents. Now, if you ever have the need, you can easily go back in time to recover anything.
Set it, then forget it.
To start using Time Machine, all you have to do is connect an external drive (sold separately) to your Mac. You’re asked if you want it to be your backup drive, and if you say yes, Time Machine takes care of everything else. Automatically. In the background. You’ll never have to worry about backing up again.
Back up everything.
Time Machine backs up your system files, applications, accounts, preferences, music, photos, movies, and documents. But what makes Time Machine different from other backup applications is that it not only keeps a spare copy of every file, it remembers how your system looked on a given day — so you can revisit your Mac as it appeared in the past.
Go back in time.
Enter the Time Machine browser in search of your long-lost files and you see exactly how your computer looked on the dates you’re browsing. Select a specific date, let Time Machine find your most recent changes, or do a Spotlight search to find exactly what you’re looking for. Use Quick Look to verify the file’s contents if you wish. Then click Restore and Time Machine brings it back to the present. Time Machine restores individual files, complete folders, iPhoto libraries, and Address Book contacts. You can even use Time Machine to restore your entire computer if need be.
How Time Machine works.
Beneath the hood, Time Machine is every bit as remarkable as it is on the outside. It’s based on stable and secure Mac OS X core technologies (like the HFS+ file system), automatically tracks file changes, and is aware of file system permissions and user access privileges. Bottom line: It’s working with more information than other backup utilities and doesn’t need to bother you for input.
