It depends on what you want. Hightail offers cheap unlimited storage at only $160 per year. However, many people don't need or want unlimited storage. The free option only gives you 2GB of storage and only lets you transfer files up to 50 MB. That won't work for many people, especially when Dropbox, Google Drive, iCloud and the rest give you between 5 and 15 GB for free. I would stick with those instead of using Hightail, unless you really need another 2GB of storage. For backup, I wouldn't use a cloud-storage app at all, since it's more expensive than my advertiser Carbonite.
