I'm not sure what you mean my HUGE files, but there are many cloud based services. iCloud only provides a limited amount of space for free. Extra storage can be purchased but it gets expensive quickly.Dropbox is a good, cheap, easy to use option, but doesn't have good support for automated backups.Another cloud storage solution is Mozy. Mozy is a backup application, so it can be scheduled to backup at certain times, after a certain amount of idle time, or even while the user is working. Mozy is inexpensive. It also provides "versioning", meaning you can restore the most recent backup, or an older version of a file from a previous backup. Dropbox doesn't do this.https://mozy.com/home/
Amazon also offers cloud based storage, which can be used for backups. It's inexpensive, but the backup tools are more difficult to use.
