I absolutely love iDrive. I have used it for years.
I TB $52/year. Everything backed up. Unlimited computers/devices. I have 9 computers and 3 phones all backed up automatically.
Even though I use source control, I occasionally mess something up. iDrive keeps 10 versions of my source files. Saved my ass several times over the years.
I'm wondering what happens when we do pass 1 TB as the the site shows only a 10TB plan for $374/year. I would like a 2TB plan(You might be able to call sales and negotiate)
Honestly though, if my only option was the 10TB plan, I would do it. It would be worth it with all of the features.
I love it.
