Several years of tax returns, some music, and even a video or two might do just fine on a free online backup plan. A bit more data than that might be well suited with a standard plan from any of the popular online backup services out there. However, if you have 10,000 MP3s, 40 ripped Blu-ray movies, and a few virtual machines that you can’t live without, an unlimited online backup plan is probably a better fit for your data. Below is a list of the best unlimited online backup plans, ranked by personal preference based on our experiences with each. Few, if any, would have trouble figuring out how to install their backup software and get everything important backed up to the cloud. Backblaze costs $7 /month for unlimited online backup for one computer, or you have the option to purchase a yearly plan for only $70 annually. It’s discounted even further if you opt for the 2-year plan. A big plus in our book is the clear, no-strings-attached, way in which Backblaze explains their unlimited plan: Carbonite Safe Basic comes in at $6 /month; Carbonite Safe Plus at $9.34 /month; and Carbonite Safe Prime at $12.50 /month. The more expensive the plan, the more features you get. You can read all those details in our review. Carbonite is a very solid company with a long history (internet-relative, of course) of keeping data securely backed up. If Backblaze doesn’t fit your needs, Carbonite is a fantastic choice! Livedrive Backup is cheaper because it works on only one computer, whereas the Pro Suite plan can be used on up to five computers. One interesting thing about Livedrive’s plans: they’re relatively inexpensive if you want to add more computers, at just $1.50 per month for each additional one. Some services force you to purchase a higher tiered plan, sometimes with more computers than you need, just to get the other one in your house on the account. Most require another full priced account altogether. Most of the elements of these plans are identical, but the Business Unlimited and Reseller options have different custom branding features. Order any of these on a yearly basis to get what equates to two months free.
