From the developer:
Time Machine works with your Mac and an external hard drive (sold separately) to automatically back up your entire Mac, including system files, applications, accounts, preferences, music, photos, movies, and documents.
Time Machine automatically makes backups every hour, every day, copying just the files that have changed since your last backup.
