With the Music app on your Mac, you can sync your library to save your tunes, but you should also do a dedicated backup.
To sync your music library:
- Launch the app
- Select Preferences at the top left side of your screen
- Select Sync Library
This will show all the music you’ve added, bought, and uploaded. The music on the Mac you’re using will appear on your other Apple devices (and PCs) after syncing with iCloud.
I would also suggest selecting the Automatic Downloads option so that when you add music to your library, it will automatically be downloaded to your Mac (as opposed to simply being stored in the “cloud”) so you can play it when you’re offline. Of course, make sure you’ve got plenty of room on your Mac’s hard drive to store all your tunes. Otherwise, move your Music library to an external drive.
Now let’s back up your music…
- Launch the Music app
- Find the Artist, Albums, or Songs you want to download
- Click the … button to bring up a pop-up menu
- Select Download to initiate the download.
Okay, so now we’ve got your tunes stored in iCloud and on your Mac. But let’s make sure we’re safe by having a third “hard” copy saved. If you’re using Apple’s Time Machine backup system and an external drive (and if you’re not, you should), your Music library and other important data should be backed up.
You can also back up your files to an external drive. First, consolidate your Music folder files. Why? Depending on how you imported items into Music, some items in your library might be stored in different locations (for example, in another folder or on another storage device).
You can consolidate all the files in your library in the Music folder—for example, to make it easier to move your library to a new computer or back it up.
Consolidate Music Files
- Launch Music
- Choose File > Library > Organize Library
- Select Consolidate files
Files remain in their original locations, and copies are placed in the default folder.
Now you can locate your Music folder on your Mac’s hard drive and drag and drop it to an external hard drive.
Voila! Now you’ve got multiple copies of all your music.
