CrashPlan made a different decision. If I was to offer an unlimited backup service, I would offer it to novice users, not a small minority of power users and professionals who were going to break the business model with TBs of data.

Let's be honest: when people see unlimited, most think "I don't have to worry about how much I'm storing" but a small group thinks "How can I take advantage of this?"

Not supporting a Linux client fixes that quickly.

I don't want to take advantage of it. I just happen to have 8TB of data to back up...

But backing up that much data over the internet isn't practical in any case.

Fixed that for you. We're just trying to maximize our resources and minimize cost. Nothing wrong with that.

CrashPlan built their system using Java and offers enterprise versions of their clients and servers. They have a very different technology stack and business model.
