It is used to play, download, and organize digital downloads of music and video (as well as other types of media available on the i Tunes Store) on personal computers running the mac OS and Microsoft Windows operating systems.The i Tunes Store is also available on the i Phone, i Pad, and i Pod Touch.
This way, if you ever need to restore, you can just pop back in Time Machine's History (or a past backup from Crash Plan or Carbon Copy Cloner, for example) to retrieve it.
If you're not employing a Mac-wide backup service (really, you should get on that), or if you just want to manually back up your i Tunes library separately, here's how to go about that.
And if you use Apple Music or i Cloud Music Library, the best way to do that is still i Tunes.
There are a few ways to back up your i Tunes library; it's important to choose one and regularly back up so that you won't have to worry about your local copy getting lost or damaged.
But to truly make sure your purchased and owned content is backed up, you'll want to download a local copy to your Mac.
Here's the best way to do so: How to download all your music from i Cloud Music Library to your Mac If you have Apple's Time Machine backup system enabled — or any other cloud- or system-based backup — your i Tunes library should automatically be covered.Officially, it is required in order to manage the audio data of an i Pod, i Phone, or i Pad, although alternative software does exist.Users can organize their music into playlists within one or more libraries, edit file information, record Compact Discs, copy files to a digital audio player, purchase music and videos through its built-in music store (i Tunes Store), download free podcasts, back up songs onto a CD or DVD, run a visualizer to display graphical effects in time to the music, and encode music into a number of different audio formats.Through the i Tunes Store, users can purchase and download music, music videos, television shows, audiobooks, podcasts, movies, and movie rentals in some countries, and ringtones, available on the i Phone and i Pod Touch (fourth generation onward).Application software for the i Phone, i Pad and i Pod Touch can be downloaded from the App Store.It also adds i Tunes LPs to the store, which provides additional media with an album.
