Best online backup options (Cloud)?

I currently use CrashPlan, but need to backup more than one computer, which doubles the price. BackBlaze used to be a top product, but don't see if even making the reviews anymore...

Looking for unlimited storage, continuous backup, image backup, good retention, all for cheap (LOL!).

Recommendations and reasoning appreciated! Thanks!

You aren't going to be able to beat the price of CrashPlan and still have the same level of safety and reliability. I prefer Carbonite myself but it will still cost more for multiple computers. Only you can determine how valuable your data is and how much you are willing to spend to protect it. Considering how much data recovery costs, assuming lost data can even be recovered (often, it cannot), unless yu can replace your data pretty much for free, shelling out the shekels for safe and reliable backups is far cheaper.
