All your files are important, and I’d strongly recommend backing up everything. Some of you may back up your documents, but it’s best not to ignore an important part of your Mac’s files: Your iTunes media. There may be a lot of money in your iTunes library, and a lot of time spent building it. After all, iTunes holds music, videos, and audiobooks that you’ve bought, as well as any CDs or DVDs that you’ve ripped. While you can replace the latter, if you lose your files, it would take a long time to get everything back.
Now if you’re short on space, there are some iTunes media files that you don’t need to back up. Here’s an overview of how to back up your iTunes media files, and which ones you need to back up.
If you look inside your iTunes Media folder — this is either in the /Music/iTunes folder of your user folder, or on an external drive, if you’ve manually changed its location — you’ll see a number of sub-folders:
Each of these folders contains a specific type of file. Two exceptions are the Automatically Add to iTunes folder, and the Downloads folder. The latter holds temporary files for iTunes downloads, and the former is a sort of watch folder that adds to iTunes any files you place in it.
You could simply back up the entire iTunes Media folder, but if you’re a bit short on space, you can exclude some of the content. Here’s what you need to know about these folders.
There are two easy ways to do this. The first is to use Time Machine, which we’ve discussed here. Just connect a hard drive to your Mac, and set it up. It’s automatic and transparent. Time Machine backs up your files every hour, and keeps old backups, so you can always be sure to find any files you’ve lost.
The second is to use dedicated backup software, such as Intego Personal Backup, which is available as part of Intego’s Mac Premium Bundle X8. Personal Backup is easy to use, and you can exclude certain folders if you need to trim the size of your backups.
I use Personal Backup and exclude a number of folders: Audiobooks, iTunes U, Mobile Applications, and Podcasts. I also have Personal Backup copy only the latest versions of my files, and delete any files from the backup that are no longer in the source. That way, may backups stay lithe and up to date.
Each time you run Personal Backup, it only backs up files that are new or modified. So if you haven’t changed anything in your iTunes library, Personal Backup checks and copies nothing. If you’ve added a few files, Personal Backup only backs up those files, leaving the rest of your existing backup intact. So while your first backup can take a long time, if you have a lot of media files, each subsequent backup is a lot quicker.
No matter which option you choose, make sure to back up your iTunes Media files. It would be a shame to lose all the music, movies, audiobooks, and other content you’ve bought or ripped.
